The series of olefin‐SO 2 copolymers prepared from the C 8 ‐C 18 even‐numbered carbon series of alpha‐olefins and sulfur dioxide have been studied. The C 16 polymer especially has high gas permeability, good biocompatibility, low, toxicity, low thrombogenicity, ease of fabrication and potential low cost. Maximum permeabilities, maximum percent elongation at the yield point and minimum density are obtained with the C 16 based polymer. An explanation is proposed involving a competitive plasticizing/side chain crystallization effect.
