These may be prepared in accordance with the procedures described below in Examples A and B.
The compounds of Formula I are easily prepared by the reaction of X--ArSO.sub.2 Ar'QAr'SO.sub.2 Ar--X (1 mole) with 2 moles of CH.sub.3 OOCC.sub.6 H.sub.4 OH (available commercially as Parasept) preferably in the presence of an anhydrous medium such as dimethyl sulfoxide or other aprotic solvent, and an alkali metal hydroxide, such as NaOH. Other esters may be used in which the methyl group is replaced by other hydrocarbon groups or in which the phenylene (--C.sub.6 H.sub.4 --) radical is replaced by other divalent aromatic radicals. Because of economics and availability, Parasept is preferred. The methyl or other hydrocarbon group may be replaced to give the corresponding acid, acid halide or other ester groups by standard methods of hydrolysis, reaction with SOCl.sub.2 or ester interchange, respectively.
Various types of polymers may be prepared from the compounds of Formula I. For example, polyesters and polyamides may be prepared by reaction with polyols and polyamines, and additional polymers may be prepared by standard, well known free radical polymerization techniques when the D of the formula contains an unsaturated group, such as vinyl, propargyl, etc.
In conducting polymerizations various solvents may be used with the polysulfones of this invention. The particular solvent used will depend on the specific polysulfone used. In many cases, the solvent may be an aprotic organic compound having a dielectric constant between 35 and 45, preferably one which is water soluble. Representative aprotic compounds are N,N-dimethylformamide, N,N-diethylformamide, N,N-dimethylmethoxyacetamide, N-methyl caprolactam, caprolactam, N,N-dimethylacetamide, N,N-diethylacetamide, dimethyl sulfoxide, N-mexthyl-.alpha.-pyrrolidone, tetramethylurea, hexamethylphosphoramide, tetramethylene sulfone, N,N,N',N'-tetramethyl-.alpha.-ethylmalonamide, N,N,N',N'-tetramethylglutaramide, N,N,N',N'-tetramethylsuccinamide, thiobis(N,N-dimethylacetamide), bis(N,N-dimethylcarbamylmethyl)ether, N,N,N',N'-tetramethylfuraramide, methylsuccinonitrile, N,N-dimethylcyanoacetamide, N,N-dimethyl-.beta.-cyano-propionamide, N-formylpiperidine and butyrolactone, etc.
Of these solvents, dimethylacetamide is most preferred. Other preferred solvents are dimethylformamide, N-methyl pyrrolidone, dimethyl sulfoxide, butyrolactone and caprolactam.
In many cases, non-aprotic solvents can be used. For example, xylene, phenol, anisole, benzonitrile, acetophenone, methylphenylether or mixtures of these with each other, the aprotic solvents or with relatively poor solvents such as benzene, toluene cyclohexane, cyclohexene, dioxane, butyl cellosolve and the like.
The concentration of the polysulfone in the solvent can be in the range of 1 to 80% by weight of polysulfone and solvent depending on the polysulfone, the solvent and the temperature used. Preferably, the concentration is between 10 and 60% by weight.
Polymerization products of the present invention have application in a wide variety of physical shapes and forms, including use as films, molding compounds, coatings, etc. The unusual heat stability and resistance to deformation at elevated temperatures in the cured state makes these compositions especially unique. When used as films or when made into molded products, these polymers, including laminated products prepared therefrom, not only possess excellent physical properties at room temperature, but they retain their strength and excellent response to work-loading at elevated temperatures for long periods of time.
Moreover, solutions of the curable compositions herein described can be coated on electrical conductors such as copper, aluminum, etc. and thereafter, the coated conductor can be heated at elevated temperatures to remove the solvent and to effect curing of the resinous composition. If desired, an additional overcoat may be applied to such insulated conductors including the use of polymeric coatings such as polyamides, polyesters, silicones, polyvinylformal resins, epoxy resins, polyimides, polytetrafluoro-ethylene, etc.
They can also be used as binders for asbestos fibers, carbon fibers and other fibrous materials in making brake linings. In addition, molding compositions and molded articles may be formed from the polymeric compositions in this invention by incorporating such fillers as asbestos, glass fibers, talc, quartz, powder, wood flour, finely divided carbon, silica, into such compositions prior to molding. Shaped articles are formed under heat, or under heat and pressure in accordance with practices well known in the art. In addition, various heat-resistant pigments and dyes may be incorporated as well as various types of inhibitors, depending on the application intended.
Various other compounds or derivatives of this invention may be prepared from compound I or from the starting dihalide compound X--A--X. For example, compound I may be reacted with an amine, NHR.sub.2, to give the compound:
R.sub.2 NOCArO--A--OArCONR.sub.2 (II)
wherein R represents hydrogen or a hydrocarbon radical, preferably of 1-20 carbon atoms. When a diamine is used, a polymer is produced having a plurality of repeating units of the structure:
--NR--R'--NR(O)CArO--A--OArC(O)-- (III)
wherein R' is a divalent aliphatic, cycloaliphatic or aromatic hydrocarbon radical.
Polymeric polyesters may be prepared by reacting compound I with approximately equimolar proportions of a polyol, HOR'OH, such as ethylene glycol, etc. Here again, the R' may be aliphatic, cycloaliphatic or aromatic. The resultant polymers have a repeating unit structure of the formula:
--OR'O(O)CArO--A--OArC(O)-- (IV)
Various unsaturated aromatic ether compounds may be prepared by the reaction of vinylaryl, allylaryl and acetylenicaryl hydroxy compounds with X--A--X to give diethers having the formula KO--A--OK (V), wherein K represents an aromatic group having a terminal vinyl or acetylene radical, such as
CH.sub.2 .dbd.CH--Ar--O--A--O--Ar--CH.dbd.CH.sub.2
CH.sub.2 .dbd.CHCH.sub.2 ArO--A--OArCH.sub.2 CH.dbd.CH.sub.2
CH.tbd.CCH.sub.2 ArO--A--OArCH.sub.2 C.tbd.CH
CH.sub.2 .dbd.C(CH.sub.3)ArO--A--O--Ar--C(CH.sub.3).dbd.CH.sub.2
Dihydroxy aromatic compounds may be reacted with approximately equimolar proportions of X--A--X, preferably with at least two moles of dihydroxy compound per mole of X--A--X to give derivatives of the formula:
HOArO--A--OArOH (VI)
These derivatives (VI) may be condensed with aldehydes such as formaldehyde to produce resins having the repeating unit formula: ##STR7##
Derivatives VI may also be reacted with aromatic dicarboxyl dihalides such as terephthalic dichloride, to give polymers having the repeating unit:
--ArO--A--OArOOCArCOO-- (VIII)
or with phosgene, etc., to give polycarbonate polymers having the repeating unit:
--ArO--A--OArOOCO--. (IX)
Reaction of polyesters IV derived from aromatic polyols, such as hydroquinone, p,p'-dihydroxydiphenyl, bis-phenol-A, etc., may be enhanced in heat resistance by reaction with the dihydroxy compounds VI or by the direct preparation of polyesters of very good heat resistance by the reaction of derivative I with the dihydroxy compound VI to give polymers having the repeating unit:
--OOCArO--A--OArCOOArO--A--OAr--. (X)
The reaction of X--A--X with HOArNH.sub.2, such as HOC.sub.6 H.sub.4 NH.sub.2 gives the diamine of the formula:
NH.sub.2 ArO--A--OArNH.sub.2 (XI)
which, when reacted with the dicarboxy compound I gives a polyamide polymer having repeating units of the formula:
--NHARO--A--OArNHOCArO--A--OArCO.sub.13 (XII)
While the formulas of the preceding compounds of this invention have been given in full, it is possible in view of the generally symmetrical nature of these compounds to abbreviate these by the use of brackets to include the duplicated portions. For example, Formula I can also be written as:
[DOOCArO--ArSO.sub.2 Ar'].sub.2 Q (I)
By reacting the X--A--X compounds with an acyl aromatic hydroxy compound such as a p-acyl-aryl hydroxide, for example m- or p-hydroxy-acetophenone, m- or p-benzoyl-phenol, 3-, 4- or 6-acetyl-naphthol-1,1-, 5- or 6-acetyl-naphthol-2, 4-acetyl-4'-hydroxy-diphenyl, 3-acetyl-4'-hydroxy-diphenyl oxide, etc. Compounds of this invention are preferred having terminal acyl groups. For example, the reaction of p-hydroxy-acetophenone with the X--A--X compound produced below in Example A gives the product:
[CH.sub.3 COC.sub.6 H.sub.4 OC.sub.6 H.sub.4 SO.sub.2 C.sub.6 H.sub.4 ].sub.2 O (XIIIa)
and with p-hydroxybenzophenone, the product is:
[C.sub.6 H.sub.5 COC.sub.6 H.sub.4 OC.sub.6 H.sub.4 SO.sub.2 C.sub.6 H.sub.4 ].sub.2 O (XIIIb)
With the X--A--X compound produced below in Example B, the products are respectively:
[CH.sub.3 COC.sub.6 H.sub.4 OC.sub.6 H.sub.4 SO.sub.2 C.sub.6 H.sub.4 ].sub.2 SO.sub.2 (XIIIc)
and
[C.sub.6 H.sub.5 COC.sub.6 H.sub.4 OC.sub.6 H.sub.4 SO.sub.2 C.sub.6 H.sub.4 ].sub.2 SO.sub.2 (XIIId)
Also included within the scope of this invention are compounds in which the terminal aromatic groups have a second --COOD group such as Ar(COOR).sub.2, Ar(COOH).sub.2 and Ar(COOX).sub.2. For example, in the preparation described in Example I, the p-hydroxy phenyl benzoate may be replaced by an equivalent amount of 4-hydroxy dimethyl phthalate to give the product
(CH.sub.3 OOC).sub.2 C.sub.6 H.sub.3 OC.sub.6 H.sub.4 SO.sub.2 C.sub.6 H.sub.4 OC.sub.6 H.sub.4 SO.sub.2 C.sub.6 H.sub.4 OC.sub.6 H.sub.3 (COOCH.sub.3).sub.2
These may be converted to the tetraacids and the tetraacid halides by the procedures described above.
This group of compounds may be represented by the formula:
(DOOC).sub.2 ArO--A--OAr(COOD).sub.2 (XIV)
In turn these tetrafunctional compounds, by using the techniques described above, may be converted to:
tetraamides: (R.sub.2 NOC).sub.2 ArO--A--OAr(CONR.sub.2) (XIVe) ##STR8## and unsaturated polymerizable derivatives:
(CH.sub.2 .dbd.CHOOC).sub.2 ArO--A--OAr(COOCH.dbd.CH.sub.2).sub.2 (XIVg)
and
(CH.tbd.CCH.sub.2 OOC).sub.2 ArO--A--OAr(COOC.tbd.CH).sub.2 (XIVh)
The polymers of formula XIVf and those produced by free radical polymerization of XIVg and XIVh are tractable products and may be of both thermoplastic and thermosetting types useful as coating materials to give solvent and heat resistant films.
The dicarboxylate groups of formula XIV wherein the members of respective pairs of carboxy groups are positioned ortho or peri to each other may be converted to polyimide polymers by using one mole of a diamine R'(NH.sub.2).sub.2 per mole of formula XIV, which has been first converted to the tetraacid chloride compound by reaction with thionyl chloride. Completion of reaction and removal of by-products and solvent gives a polymer having the repeating unit structure:
--OAr(CO).sub.2 N--R'--N(OC).sub.2 ArO--A-- (XV)
The R' in the diamine is preferably aromatic in which case R' may be defined as Ar. Typical diamines of the NH.sub.2 --Ar--NH.sub.2 formula are those having the Ar groups as defined above.

Aldehyde Condensation Polymers Having the Repeating Unit Formula
--CHR--Ar"(OH)O--A--OAr"(OH)--(wherein Ar" is a trivalent aromatic radical) (VII)
Into a one-liter flask equipped with a stirrer, condenser and a nitrogen gas inlet tube is placed 400 ml of dimethyl sulfoxide and 166.5 gms (0.25 mole) of [HOC.sub.6 H.sub.4 OC.sub.6 H.sub.4 SO.sub.2 C.sub.6 H.sub.4 ].sub.2 O (VIa) and 0.4 gm of triethylamine. In a separate flask there is placed 15 gms (equivalent to 0.5 mole CH.sub.2 O) of paraformaldehyde. A stream of nitrogen is fed into this flask and through a tube into the first flask below the surface of the solution therein. The solution in the first flask is stirred and maintained at 90.degree. C. while a bunsen burner is applied to the second flask containing the paraformaldehyde. As the paraformaldehyde is sublimed it is carried by the stream of nitrogen into the solution in the first flask. After the transfer of the paraformaldehyde (or formaldehyde) has been completed, the temperature of the solution is maintained for another 4 hours. Most of the dimethyl sulfoxide is removed by distillation at 15 mm. Hg pressure in a rotary evaporator. The product is dried in a vacuum oven at 15 mm. pressure for 24 hours. Then the product is pulverized and placed in a compression mold and molded at 250.degree. C. and 2500 psi to give a tough, insoluble, heat-resistant product.
Similar results are obtained with the dihydroxy compounds of VI b, c, d, e, f, g, h, i and j.

This mixture is heated to reflux under nitrogen and the water removed by the Dean-Stark trap. When no more water is collected in the trap, toluene is distilled from the mixture and an additional 100 ml of dimethylsulfoxide is added. To this solution is added 156.6 gms.

In the above formulas, n is an integer having a value of 1-50 or more preferably 1-20. When n equals 1, the compound is monomeric and when n equals 2 or more, the composition is polymeric. In either case the terminal valencies may be satisfied with various groups such as may be on the starting compounds or derived therefrom such as H, R, RCO, etc. Again the terminal groups will depend on the manner in which the repeating unit structure is recited or divided. For example, in the generic formula j' which is given above as
(1) H--[OR'O(O)CArO--A--OCArC(O)--].sub.n OH wherein n is 1-50 or more);
this may be rewritten several times as follows with n' which has a value of 0-49 or more, preferably 0-19.

It may be seen therefore that various portions of the respective formulas may be taken as the repeating unit.
When n of formula (1) has a value of 1, the compound is monomeric and when n' of formulas (2) through (5) has a value of zero, the compound is monomeric. With higher values of either, the compound is a polymer having a plurality of repeating units.
These represent five ways of writing formulas for the same compound whereby the arrangement of the repeating unit is given a modified sequence and the terminal groups are modified accordingly. In these formulas the repeating unit as given within the brackets for formulas (2) through (5) may be selected almost arbitrarily thereby causing a variation in the terminal groups at the left and right ends of the respective formulas. While the formula arrangement of (1) is preferred, the various arrangements of (2) through (5) are permissible.
Moreover while the terminal groups are generally in the starting components, it is also possible that during the processing a terminal group may be converted to another group. For example, when an acid chloride is a terminal group in a starting component, the active chlorine at one terminal of the long chain may come into contact with water during processing and be converted to OH. Such reactive groups also may subsequently be deliberately converted to other groups, such as esters, by reaction with an alcohol.
It is preferred in the preparation of the above polymers that approximately equimolar amounts of the components or reagents should be used. In such cases the terminal group at one end will be derived from one component and the group at the other end will be derived from the other component. When one component or reagent is used in excess, the resultant polymer generally has both terminal groups derived from the component used in excess. However the use of a component in considerable excess will cause a limit on the molecular weight of the product and generally the more the excess the shorter will be the length of the resulting polymer molecule.
As disclosed above, the compositions of this invention hava a variety of utilities. For example, compositions of formulas I, II, VI, XI, XIII and XIV are particularly useful for blending with polyethylene terephthalate (PET) and polybutyleneterephthalate (PBT) to upgrade and improve their properties and also to improve their crystallization rates. Compositions of formulas V and XV can be used as intermediates in the formation of polymeric products of good properties. The polymeric compositions of formulas III, IV, VII, VIII, IX, X and XII give tough films and coatings of good heat and solvent resistance and may be molded to give products of excellent strength and work-loading properties. The polymeric compositions may be cured by heat and pressure with and without various fillers, modifiers, etc., to give shaped products of excellent properties.
