Resin composition and production thereof.

摘要

A resin composition comprising (A) a saponified ethylene-vinyl acetate copolymer having an ethylene content of 20 to 60 mole percent and a saponification degree of not less than 90 mole percent, (B) a polyolefin resin, (C) a carboxylic acid-modified polyolefin resin and (D) a lower fatty acid alkaline earth metal salt, characterized in: that the proportion of (A) relative to the total amount of (A) plus (B) plus (C) is 0.3 to 0.7 on the weight basis; that the composition contains the carbonyl group in an amount of 0.002 to 0.05 equivalent per 100 grams of the total of (B) plus (C); and that the equivalent ratio between (D) and the carbonyl group in (C) is 0.5 to 5, and a method of producing the resin composition are provided.
