Abstract

A prosthetic device comprising at least one part consisting of a polymer composition comprising at least one polyarylene (P1) and at least one polyarylether selected from the group consisting of poly(aryl ether ketone)s (P2) and poly(aryl ether sulfone)s (P3).

Claims

1. A prosthetic device comprising at least one part consisting of a polymer composition comprising at least one polyarylene (P1) and at least one polyarylether selected from the group consisting of poly(aryl ether ketone)s (P2) and poly(aryl ether sulfone)s (P3).

2. The prosthetic device according to claim 1, wherein the polyarylene (P1) is a kinked rigid-rod polymer.

3. The prosthetic device according to claim 1, wherein more than 90 wt. % of the recurring units of the polyarylene (P1) are recurring units (R1) of one or more formulae consisting of an optionally substituted phenylene group which is linked by each of its two ends to two other optionally substituted phenylene groups via a direct C—

C linkage.

4. The prosthetic device according to claim 3, wherein said recurring units (R1) are a mix of recurring units (R1-a) with recurring units (R1-b), said recurring units (R1-a) being optionally substituted p-phenylenes and said recurring units (R1-b) being optionally substituted m-phenylenes.

5. The prosthetic device according to claim 4, wherein the mole ratio of the recurring units (R1-b), based on the total number of moles of the recurring units (R1-a) and (R1-b), ranges from 30% to 70%.

6. The prosthetic device according to claim 1, wherein the recurring units of the polyarylene (P1) consist of a mix of p-phenylene substituted by a phenylketone group with unsubstituted m-phenylene in a mole ratio p-phenylene:

m-phenylene of from 70;

30 to 30;

70.

7. The prosthetic device according to claim 1, wherein the polyarylether is a poly(aryl ether sulfone) (P3).

8. The prosthetic device according to claim 7, wherein the poly(aryl ether sulfone) (P3) is a polyphenylsulfone.

9. The prosthetic device according to claim 1, wherein the polyarylether is a poly(aryl ether ketone) (P2).

10. The prosthetic device according to claim 9, wherein the poly(aryl ether ketone) (P2) is a poly(ether ether ketone).

11. The prosthetic device according to claim 1, which is suitable to act as replacement of a missing or defective animal or human body part.

12. The prosthetic device according to claim 1, which is suitable to supplement, or to act as reinforcement of a defective body part.

13. The prosthetic device according to claim 1, which is an implantable orthopaedic prosthesis.

14. The prosthetic device according to claim 13, which is selected from the group consisting of hip joints, knee prosthesis and spinal disc orthoprosthesis.

15. The prosthetic device according to claim 1, which is an implant.

16. The prosthetic device according to claim 1, which is a denture or a partial denture.

18. A surgical method, which involves implanting the prosthetic device according to claim 1 in the body of an animal or a human.

19. The surgical method according to claim 18, wherein the prosthetic device is implanted in the body of a patient.

20. The surgical method according to claim 18, wherein the prosthetic device is a cosmetic implant.

17. A part of a prosthetic device, said part consisting of a polymer composition comprising at least one polyarylene (P1) and at least one polyarylether selected from the group consisting of poly(aryl ether ketone)s (P2) and poly(aryl ether sulfone)s (P3).
