PURPOSE: To provide a composition containing a diene-acrylic copolymer, methyl methacrylate and N-arylmaleimide and having high fluidity and balanced and excellent heat-resistance and impact-resistance. n CONSTITUTION: The objective composition containing 1W50wt% fattened rubbery copolymer is obtained by compounding (A) a diene-acrylate graft copolymer produced by (1) mixing (i) 100pts.(wt.) (in terms of polymer) of a rubber copolymer latex obtained by the emulsion polymerization of a 2W8C alkyl acrylate and 1,3-butadiene with (ii) 0.1W5pts. of polymer latex of an acid group-containing copolymer obtained by the emulsion polymerization of an unsaturated acid unit and a 1W12C alkyl acrylate and/or an alkali metal or alkaline earth metal salt of an oxyacid of an element of the 2nd or 3rd period of the group IIIAWVIA, and (2) polymerizing 10W1,000pts. of methyl methacrylate or styrene in the presence of 100pts. of the above latex fattened to an average particle diameter of 0.12W0.4μm and (B) a thermoplastic resin produced by polymerizing methyl methacrylate and N-arylmaleimide. n COPYRIGHT: (C)1986,JPO&Japio |
