| 摘要 |
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. |

1. A prosthetic device comprising at least one part consisting of a material consisting of:
at least one polyarylene (P2) comprising efficient arylene recurring units (R2), wherein the efficient arylene recurring units (R2) are a mix (M2) consisting of:
less than 70 mole %, down to 0 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 100 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, and optionally at least one additive selected from the group consisting of fibrous reinforcing agents, char promoters, particulate fillers, nucleating agents, adhesion promoters, compatibilizers, curing agents, lubricants, metal particles, mold release agents, organic and/or inorganic pigments, dyes, flame retardants, smoke-suppressing agents, heat stabilizers, antioxidants, UV absorbers, tougheners, plasticizers, anti-static agents, and melt viscosity depressants, wherein the prosthetic device is an orthopaedic prosthesis, a dental structure, an artificial body part selected from the group consisting of limbs, eyes, and implants, or a fixed prosthetic anatomical device. |
