Abstract
Abstract Flame-resistant resinous molding of ethylene-vinyl alcohol copolymer, 5 to 50 parts of a halo-organocompound, 0.2 to 10 parts of a metallic soap and 0 to 30 parts of antimony trioxide, said parts being parts by weight per 100 parts by weight of ethylene-vinyl alcohol copolymer. The blending of a thermoplastic resin having a solubility parameter of 8 to 12 based on Small''s equation to the composition improves the molding property of the composition.
