Claims
- 1. An ordered copolyetherketone consisting essentially of the two repeat units represented by the formulas ##STR10## where said (a) and (b) units occur at a ratio in the range of 80:20 to 25:75, said copolyetherketone being characterized by one or more of the following properties:
- (i) having a dH which is at least 5 J/g greater than the dH of a copolyetherketone of the same gross composition wherein the repeat units occur in random sequence, dH being the heat of fusion,
- (ii) having a dT which is at least 5.degree. C. less than the dT of a copolyetherketone of the same gross composition wherein the repeat units occur in random sequence, dT being the difference between the melting point and the temperature of onset of crystallization, and
- (iii) having a Tm which is at least 5.degree. C. greater than the Tm of a copolyetherketone of the same gross composition wherein the repeat units occur in random sequence, Tm being the melting point.
- 2. A copolyetherketone of claim 1 in which dH is at least 5 J/g greater than the dH of a copolyetherketone of the same gross composition wherein the repeat units occur in random sequence.
- 3. A copolyetherketone of claim 1 in which dT is at least 5.degree. C. less than the dT of a copolyetherketone of the same gross composition wherein the repeat units occur in random sequence.
- 4. A copolyetherketone of claim 1 in which Tm is at least 5.degree. C. greater than the Tm of a copolyetherketone of the same gross composition wherein the repeat units occur in random sequence.
- 5. A copolyetherketone of claim 1 characterized by one or more of the following properties:
- (i) having a dH which is at least 10 J/g greater than the dH of a copolyetherketone of the same gross composition wherein the repeat units occur in random sequence,
- (ii) having a dT which is at least 10.degree. C. less than the dT of a copolyetherketone of the same gross composition wherein the repeat units occur in random sequence, and
- (iii) having a Tm which is at least 10.degree. C. greater than the Tm of a copolyetherketone of the same gross composition wherein the repeat units occur in random sequence.
- 6. A copolyetherketone of claim 1 or 5 in which the ratio of (a) units to (b) units is in the range of 70:30 to 30:70.
- 7. A copolyetherketone of claim 1 or 5 in which the ratio of (a) units to (b) units is about 50:50.
- 8. A copolyetherketone of any of claims 1, 2, 3, 4 or 5 which comprises said (a) units and said (b) units in alternating order.
- 9. A copolyetherketone of any of claims 1, 2, 3, 4 or 5 which comprises said (a) units or said (b) units in blocks.
- 10. A process for preparing a copolyetherketone of any of claims 1, 2, 3, 4 or 5 consisting essentially of contacting appropriate quantities of a bis-substituted benzene, where said bis-substituted benzene is selected from bis-(4-phenoxybenzoyl)-1,4-benzene and bis-(4-phenoxybenzoyl)-1,3-benzene and (a) optionally, appropriate quantities of a first phthalyl chloride and diphenyl ether in the presence of Friedel-Crafts catalyst, said first phthalyl chloride being terephthalyl chloride when said bis-substituted benzene is bis-(4-phenoxybenzoyl)-1,4-benzene and being isophthalyl chloride when said bis-substituted benzene is bis-(4-phenoxybenzoyl)-1,3-benzene, followed by (b) appropriate quantities of a second increment of phthalyl chloride and diphenyl ether in the presence of Friedel-Crafts catalyst, said second increment of phthalyl chloride comprising isophthalyl chloride and, optionally, terephthalyl chloride, when said bis-substituted benzene is bis-(4-phenoxybenzoyl)-1,4-benzene and comprising terephthalyl chloride and, optionally, isophthalyl chloride when said bis-substituted benzene is bis-(4-phenoxybenzoyl)-1,3-benzene, the amount of said catalyst in (a) or (b) being the sum of about one mole per each mole of diphenyl ether, four moles per mole of bis-substituted benzene and two moles per each mole of phthalyl chloride.
- 11. The process of claim 10 in which said bis-substituted benzene is
- bis-(4-phenoxybenzoyl)-1,4-benzene, and step (a) is omitted.
- 12. The process of claim 10 in which the resulting copolyetherketone has (a) units and (b) units in a ratio of about 50:50.
- 13. A shaped article obtained by extruding, compression molding or injection molding a copolyether ketone of claim 1.
- 14. A shaped article obtained by extruding, compression molding or injection molding a copolyether ketone of claim 5.
- 15. A composite structure consisting essentially of (a) a copolyetherketone of claim 1 and (b) either a fibrous substrate or a particulate filler.
- 16. A composite structure consisting essentially of (a) a copolyetherketone of claim 5 and (b) either a fibrous substrate or a particulate filler.
