The present invention relates to novel fluorocarbon terminated oligo- and poly-carbonates, to compositions comprising an organic material, preferably a synthetic polymer such as a polycarbonate, polyester, polyacrylate or polymethyacrylate or their mixtures, blends or alloys, and to the novel surface modifiers, as well as the use of the novel compounds as reducer of surface energy of organic materials. Polymers with such a reduced surface energy possess an “easy to clean”, “self-cleaning” “antisoiling” “soil-release”, “antigraffiti”, “oil resistance”, “solvent resistance”, “chemical resistance”, “self lubricating”, “scratch resistance”, “low moisture absorption” and “hydrophobic” surface.
For articles prepared from thermoplastic polymers in certain areas, there is a definite need for easy self-cleaning properties for thermoplastic glazing, particularly polycarbonate clear sheets and films used in glazing applications. Self-cleaning may occur by rain water running over the surface of a sheet. Easy self-cleaning is important in order to maintain high light transmission properties of transparent or translucent sheet and to minimize build up of unwanted materials on the surface of the sheet. This would also dramatically lower the frequency of cleaning roofing or glazing in buildings, covered walkways, conservatories, automotive and transportation applications, and the like. This would also be advantageous for decorative translucent thermoplastic sheet such as opal white or bronze thermoplastic sheet.
WO-A-03/057767 discloses polycarbonate sheets having on the outer surface a coating composition having a hydroxy-functional silicone modified acrylate polymer additive in sufficient amount. This allows ease of removing solid particles (dirt) and/or liquids on the surface by reducing the adhesion of such particles and/or liquids to the substrate. The contact angle of a water droplet on the commercially available polycarbonate sheet is about 66° and on the treated sheet about 101°.
WO-A-01/74946 discloses dendrimer additives incorporated in thermoplastic resins (such as polycarbonate resins) are effective to alter the surface characteristics of the thermoplastic resin. Such compositions can be injection molded to produce articles in which the dendrimer additive is concentrated at the surface of the article to alter the properties of the resin. By selection of the type of dendrimer additive, the resulting characteristics of the molded article may be controlled.
The use of various fluorochemical compositions on fibers and fibrous substrates, such as for example textiles, carpets, paper, leather and non-woven webs to impart oil and water repellency is known for example in U.S. Pat. No. 6,127,485. This reference discloses hydrophobic and oleophobic fibers, films and molded articles comprising synthetic organic polymer wherein dispersed within the fiber, fabric or molded article and present at the surface of the fiber, fabric or molded article are fluorochemical compounds.
It has now been found that new fluorocarbon terminated oligo- and poly-carbonates are useful for various technical applications such as reducers of surface energy for organic materials, preferably polycarbonates, polyesters, polyacrylates or polymethyacrylates or their mixtures, blends or alloys. Polymers with such a reduced surface energy possess an “easy to clean”, “self-cleaning” “antisoiling”, “soil-release”, “antigraffiti”, “oil resistance”, “solvent resistance”, “chemical resistance”, “self lubricating”, “scratch resistance”, “low moisture absorption” and “hydrophobic” surface.

The compounds of the formula I can be prepared in per se known manner. In a typical reaction procedure, a fluoro alcohol is treated with bis(2,4-dinitrophenyl)carbonate (DNPC) to give in situ 2,4 dinitrophenyl carbonate of the fluoro alcohol. This derivative can easily be isolated and treated separately by for example hydroxy terminated bisphenol A oligomers of various molecular weights. However, for simplicity, the process is preferably carried out in one pot.

Polymers which are also suitable are those predominantly containing ester bonds, but which can also contain other bonds, e.g. polyester amides or polyester imides.
Polyesters containing aromatic dicarboxylic acids have become of the greatest importance, especially the polyalkylene terephthalates.

Particularly suitable polyesters are PEN, PTT, PET, PETG (glycol-modified polyethylene terephthalate) or PBT and corresponding copolymers or blends thereof. PET and its copolymers are particularly preferred.
As esters of carboxylic acid, polycarbonates (PC) are the simplest polyesters. Polycarbonates are obtained, for example from bisphenol A and phosgene or phosgene-analogon such as trichloromethylchloroformate, triphosgene or diphenylcarbonate by condensation, in the latter case usually with addition of a suitable transesterification catalyst, for example a boron hydride, an amine, e.g. 2-methylimidazole, or a quaternary ammonium salt.

The polycarbonates can be branched by suitable amounts of more than difunctional monomers (examples as stated above).
In addition to blends of PES and PC, i.e. in particular PBT/PC and PET/PC, polymers to be used according to this invention are suitably also PC/ABS and ternary blends, such as blends of PBT/PC/ABS, PBT/PET/PC, PBT/PET/PC/ABS or PBT/PC/ASA.
The blends are prepared in customary manner from the starting polymers. The preferred PES component is PBT and the preferred PC component is a PC based on bisphenolA. The ratio of PES to PC is preferably from 95:5 to 5:95, a ratio wherein one component provides at least 70% being particularly preferred.
Owing to transesterification reactions, all PES/PC blends usually comprise are more or less large proportion of block copolymer structures, i.e. part of the blend is in the form of a PC/PES block copolymer. The inventive enhancement of the properties increases the compatibility of the polymers with one another. However, it is also possible to increase the compatibility with so-called compatibilisers. In the present case, these may be, for example, polyester/polycarbonate copolymers or also polyarylates (=aromat. polyester).
To be singled out for special mention is the efficacy of the novel compounds of the formula I as reducers of surface energy of the organic materials. Organic materials with low surface energy have intrinsically better properties like for example water and oil repellency, hydrophobicity, barrier properties, easy to clean, self cleaning, antigraffiti or solvent resistance.
The compounds of the formula I will preferably be added to the organic material to be treated in concentrations of 0.1 to 20%, preferably 0.1 to 10%, typically 1 to 5%, based on the weight of said material.
In addition to comprising the compounds of the formula I, the inventive compositions may comprise further additives, typically the following:

The further additives are typically used in concentrations of 0.01 to 10%, based on the total weight of the material to be treated.
The novel compounds of the formula I can be used in particular together with phenolic anti-oxidants, light stabilizers and/or processing stabilizers.
Incorporation of component (b) and, if desired, further additives into the synthetic polymers is carried out by known methods, for example before or during compounding, extrusion, co-extrusion or else by applying the dissolved or dispersed compounds to the synthetic polymer, if appropriate with subsequent slow evaporation of the solvent.
The present invention also relates to a composition in the form of a masterbatch or concentrate comprising component (a) in an amount of from 5 to 90% and component (b) in an amount of from 5 to 80% by weight.
Component (b) and, if desired, further additives, can also be added before or during polymerisation or before crosslinking.
Component (b), with or without further additives, can be incorporated in pure form or encapsulated in waxes, oils or polymers into the synthetic polymer.
Component (b), with or without further additives, can also be sprayed onto the synthetic polymer. It is able to dilute other additives (for example the conventional additives indicated above) or their melts so that they too can be sprayed together with these additives onto the polymer. Addition by spraying on during the deactivation of the polymerization catalysts is particularly advantageous, it being possible to carry out spraying using, for example, the steam used for deactivation.
In the case of spherically polymerized polyolefins it may, for example, be advantageous to apply component (b), with or without other additives, by spraying.
The synthetic polymers prepared in this way can be employed in a wide variety of forms, for example as foams, films, fibres, tapes, moulding compositions, as profiles or as binders for coating materials, especially powder coatings, adhesives, putties or especially as thick-layer polyolefin mouldings which are in long-term contact with extractive media, such as, for example, pipes for liquids or gases, films, fibres, geomembranes, tapes, profiles or tanks.

In order to evaluate the repellency properties of the new compounds of the formula I in PP non wovens, they are incorporated in the polymer according to the following procedure:
A concentrate of the compounds of the formula I is made in polypropylene. The PP used is PP3505 from ExxonMobil (melt flow rate 400 g/10 min). Appropriate amounts of each compound are added to the PP to obtain 10% active compound as a concentrate. The concentrate is mixed by tumbling and then extruded in a twin-screw extruder (Leistritz MIC 27/GL-32D). The zone temperatures are 125, 150, 175, 175 and 175° C. to last zone. The melt ternperature is measured and is 185° C. The residence time is 60 seconds. The screws ®™ is adjusted to obtain a production rate of 100 g/minute. The molten concentrate mixture exits via a two orifice round die. The molten material is immediately cooled and solidified in a cold-water trough. The polymer string is then granulated by a Conair/Jetro 304 pelletizer.
Formulations containing 1 to 2% by weight of the compound are obtained by tumbling the appropriate amount of the 10% concentrate with the appropriate amount of polypropylene. This PP is Exxon Mobil PP3546 (melt flow rate 1200 g/10 min).
Meltblown process: 500 grams of the 1 to 2% mix so obtained is then passed through a 6-inch non-woven melt blowing pilot line. The following conditions were used for the preparation of the meltblown non-wovens: Extrusion temperature profile of 175, 215, 240° C. The adapter and die zones at 240° C. The furnace exit pipes at 205, 220 and 240° C. Air valve open to 15%. Die output of 0.45 g/minute. Die to collector distance of 30 cm. Collector ®™ is set to produce a fabric weight of 40 g/m2.
Repellency properties: The produced non-woven samples are evaluated on their water/alcohol repellency behavior similar to INDA (International Non-woven and Disposables Association) test method 80.8 (99). The wetting behavior of the samples is tested with a series of water/isopropanol mixtures. The observation of the wetting behavior is rated from 0 (water wetting, no repellency) to 1O (optimum water repellency). The non-woven samples are evaluated in the oil repellency test similar to AATCC test method 118-1997/ISO 14419. This test follows the same concepts of the already described for water repellency test method, but using, as test solvents, a series of hydrocarbons. The observation of the wetting behavior is rated from 0 (no repellency) to 8 (optimum repellency). The samples are evaluated without thermal treatment and after a thermal treatment (e.g. 130° C. for 10 minutes). The results are summarized in Table 5.
