PURPOSE:To provide a resin compsn. having excellent developability and resistance to weather, impact and thermal decomposition, by blending a styrene/acrylonitrile/methyl methacrylate terpolymer, etc. with an ABS resin. CONSTITUTION:At least two compds. selected from among an arom. vinyl compd. (e.g. styrene), a vinyl cyanide compd. (e.g. acrylonitrile) and an alkyl ester of an unsaturated carboxylic acid (e.g. methyl methacrylate) are grafted onto a non-conjugated diene rubber (e.g. an ethylene/propylene copolymer) to obtain a graft polymer. 10-90wt% graft polymer is mixed with 90-10wt% arom. vinyl compd./vinyl cyanide comped./alkyl ester of unsaturated carboxylic acid terpolymer (e.g. a styrene/acrylonitrile/methyl methacrylate terpolymer) to obtain the titled resin compsn. |
