PURPOSE:To obtain the title composition excellent in degree of matting, uniformity of mating, matting property such as prevention of formation of silver surfaces and mechanical properties, by mixing a specified thermoplastic rubber- reinforced aromatic vinyl resin with a bisoxazoline compound. CONSTITUTION:A thermoplastic rubber-reinforced aromatic vinyl resin (A) is obtained by polymerizing 0.02-10wt.% ethylenically unsaturated carboxylic acid (b) [e.g., (meth)acrylic acid], an aromatic vinyl compound (c) [e.g., (alpha- methyl)-styrene], an unsaturated nitrile (d) [e.g., (meth)acrylonitrile] and/or an unsaturated carboxylate (e) [e.g., (meth)acrylate] and, optionally, other monomers (f) copolymerizable therewith (e.g., N-phenylmaleimide) in the presence of 5-40wt.% rubbery polymer (a) such as polybutadiene or an ethylene/ propylene polymer. 100pts.wt. component A is mixed with 0.01-2.0pts.wt. bisoxazoline compound (B) [e.g., 2,2'-(1,3-phenylene)-bis(2-oxazoline)].
