Abstract

Provided are resin compositions comprising the following (A), (B), (C), which is at least one member selected from (C.sub.1) through (C.sub.3) and (D): PA0 (A): a polyolefin, PA0 (B): a saponified product of an ethylene-vinyl acetate copolymer having an ethylene content of 20 to 65 mol % and a saponification degree of vinyl acetate component of at least 96%, PA0 (C): (C.sub.1): at least one inorganic substance selected from titanium oxide, talc, calcium carbonate, mica and absorptive inorganic materials, PA1 (C.sub.2): at least one compound selected from the group consisting of metal salts of higher fatty acid having 8 to 22 carbon atoms, metal salts of ethylenediaminetetraacetic acid and hydrotalcite, and PA1 (C.sub.3): a polyolefin modified with an unsaturated carboxylic acid or derivatives thereof; and, PA0 (D): a saponified product of an ethylene-vinyl acetate copolymer having an ethylene content of 68 to 98 mol % and a saponification degree of vinyl acetate component of at least 20%. The compositions of the present invention have excellent compatibility within themselves and significantly solve the problems, upon molding, of molding instability such as charred resin on screw, …
