Patent ID: 8592531

Claim:
A prosthetic device comprising at least one part consisting of a material comprising at least one polyarylene (P 1 ) and at least one polyarylene (P 2 ), wherein the efficient arylene recurring units (R 1 ) of the polyarylene (P 1 ) are a mix (M 1 ) consisting of: at least 70 mole %, based on the total number of moles of efficient arylene recurring units (R 1 ), 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 (R 1 ), 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 (R 2 ) of the polyarylene (P 2 ) are a mix (M 2 ) consisting of: less than 70 mole %, based on the total number of moles of efficient arylene recurring units (R 2 ), 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 (R 2 ), of kink-forming arylene units (Rb), said kink-forming arylene units being optionally substituted by at least one monovalent substituting group, and further wherein said prosthetic device is: an orthopaedic prosthesis comprising a manufactured replacement for an end and/or an articulating surface of a bone; a manufactured replacement for a portion of a bone distant from an articulating surface; or an artificial body part selected from the group consisting of limbs, eyes, and implants.
