Abstract
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.
