    • Medical device (Δ) comprising at least one part (π) consisting of a polymer material (M) comprising at least one kinked rigid-rod polyarylene (P) of which more than 50 wt. % of the recurring units are recurring units (R) of one or more formulae consisting of an optionally substituted arylene group which is linked by each of its two ends to two other optionally substituted arylene groups via a direct C—C linkage. The recurring units (R) are a mix (μ) consisting of (i) between 0 and 75 mole %, of rigid rod-forming arylene units (Ra) and (ii) between 25 and 100 mole % of kink-forming arylene units (Rb), both contents being based on the total number of moles of the recurring units (R). Arylene units (Ra) and/or (Rb) may be optionally substituted by at least one monovalent substituting group.
    • 医疗装置(Delta)包括由聚合物材料(M)组成的至少一部分(pi),所述聚合物材料(M)包含至少一个扭结的刚性棒聚亚芳基(P),其中大于50wt。 重复单元的百分比是由通过直接C-C键连接到其两端中的每一个连接到两个其它任选取代的亚芳基的任选取代的亚芳基组成的一个或多个式的重复单元(R)。 重复单元(R)是由(i)0至75摩尔%的刚性棒形成亚芳基单元(Ra)和(ii)25-100摩尔%的扭结形成亚芳基单元组成的混合物(μ) (Rb),两者的含量均基于重复单元(R)的总摩尔数。 亚芳基单元(Ra)和/或(Rb)可任选被至少一个一价取代基取代。
