Abstract

PURPOSE:A resin composition useful as a molded article such as tube, tape, etc., having improved transparency, flame retardance, and flexibility, etc., obtained by blending a vinylidene fluoride-containing polymer having specific heat of fusion with a polyfunctional monomer. CONSTITUTION:A vinylidene fluoride-containing polymer (e.g., polyvinylidene fluoride, etc.) having <=9cal/g heat of fusion is blended with a polyfunctional monomer (e.g., trimethylolpropane trimethacrylate, etc.), to give the aimed composition. The composition is press molded into a sheet and crosslinked by electron beam rays irradiation, to give a molded article.
