Polymer composition having gas permeability

Abstract

Abstract PURPOSE:A polymer composition having gas permeability having improved mechanical strength and light resistance, obtained by blending a polytrimethylvinylsilane compound having a number-average molecular weight of >= a specific value with a specific silicon-containing substituted polyacetylene compound. CONSTITUTION:(A) 5-90wt% polytrimethylvinylsilane compound having >=100,000, preferably >=200,000 number-average molecular weight and (B) 95- 10wt% polymer having one or more structural units shown by the formula (R<1> is H, or lower alkyl; R<2>, R<3>, and R<4> are H, 1-8C monofunctional hydrocarbon group, or silicon atom-containing monofunctional organic group) obtained by homopolymerizing (copolymerizing) a silicon-containing substituted acetylene compound are dissolved in a solvent (benzene, toluene, etc.), to give the desired uniform composition solution. The composition is cast or molded from the composition solution by casting or dry or wet spinning, etc. into a film, or fiber, etc., and the solvent is removed to give a molded article.
