1. A prosthetic device comprising at least one part consisting of a material comprising at least one polyarylene (P2), of which the efficient arylene recurring units (R2) are a mix (M2) consisting of:
- less than 70 mole % based on the total number of moles of efficient arylene recurring units (R2), of rigid rod-forming arylene units (Ra), said rigid rod-forming arylene units (Ra) being optionally substituted by at least one monovalent substituting groupwithmore than 30 mole %, up to 90 mole %, based on the total number of moles of efficient arylene recurring units (R2), of kink-forming arylene units (Rb), said kink-forming arylene units being optionally substituted by at least one monovalent substituting group.

Abstract
A prosthetic device made of a first specific type of polyarylene, taken alone or in combination with a second specific type of polyarylene, featuring some unexpected advantages such as a very high strength and stiffness, good elongation properties, high chemical resistance, good biocompatibility as well as an outstanding impact resistance.

14. A prosthetic device comprising at least one part consisting of a material comprising at least one polyarylene (P1) and at least one polyarylene (P2),
wherein the efficient arylene recurring units (R1) of the polyarylene (P1) are a mix (M1) consisting of: -
at least 70 mole %, based on the total number of moles of efficient arylene recurring units (R1), of rigid rod-forming arylene units (Ra), said rigid rod-forming arylene units (Ra) being optionally substituted by at least one monovalent substituting group with from 5 to 30 mole %, based on the total number of moles of efficient arylene recurring units (R1), of kink-forming arylene units (Rb), said kink-forming arylene units being optionally substituted by at least one monovalent substituting group; and wherein the efficient arylene recurring units (R2) of the polyarylene (P2) are a mix (M2) consisting of; less than 70 mole %, based on the total number of moles of efficient arylene recurring units (R2), of rigid rod-forming arylene units (Ra), said rigid rod-forming arylene units (Ra) being optionally substituted by at least one monovalent substituting group with more than 30 mole %, up to 90 mole %, based on the total number of moles of efficient arylene recurring units (R2), of kink-forming arylene units (Rb), said kink-forming arylene units being optionally substituted by at least one monovalent substituting group. - View Dependent Claims (3, 5, 6, 7, 10, 12, 13)

22. A surgical method, which involves implanting a prosthetic device in the body of an animal or a human, wherein said prosthetic device comprises at least one part consisting of a material comprising at least one polyarylene (P2), of which the efficient arylene recurring units (R2) are a mix (M2) consisting of:
-
less than 70 mole %, based on the total number of moles of efficient arylene recurring units (R2), of rigid rod-forming arylene units (Ra), said rigid rod-forming arylene units (Ra) being optionally substituted by at least one monovalent substituting group with more than 30 mole %, up to 90 mole %, based on the total number of moles of efficient arylene recurring units (R2), of kink-forming arylene units (Rb), said kink-forming arylene units being optionally substituted by at least one monovalent substituting group. - View Dependent Claims (23, 24, 25)
