Abstract
A thermoplastic resin composition of high heat resistance and high impact resistance is described, comprising: (A) 5 to 85% by weight of a copolymer prepared from 40 to 85% by weight of a monomer mixture of 2-isopropenylnaphthalene (2-IPN) and .alpha.-methylstyrene (.alpha.-MeSt), the proportion of 2-IPN being 5 to 70% by weight based on the total weight of 2-IPN and .alpha.-MeSt, 7.5 to 35% by weight of acrylonitrile, and 0 to 40% by weight of a vinyl monomer copolymerizable with the foregoing monomers; (B) 1 to 40% by weight of a graft copolymer prepared by graft polymerization of 15 to 50 parts by weight of at least one monomer as the graft component selected from the group consisting of methacrylic acid alkyl esters, acrylic acid alkyl esters, aromatic vinyl compounds, and vinyl cyan compounds onto 50 to 85 parts by weight of a butadiene-based rubber or alkyl acrylate-based rubber as the rubber component, provided that the sum of the graft and rubber components is 100 parts by weight; and (C) 10 to 90% by weight of a polycarbonate.
