Abstract
A thermoplastic resin composition of high heat resistance and high impact resistance is described, comprising: (A) 50 to 90% by weight of a copolymer prepared by copolymerization of 10 to 35% by weight of acrylonitrile, 60 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, and 0 to less than 10% by weight of a vinyl monomer copolymerizable with the foregoing monomers; and (B) 10 to 50% by weight of a graft copolymer prepared by polymerizing 15 to 50 parts by weight of at least one monomer selected from the group consisting of aromatic vinyl compounds, vinyl cyanides, methacrylic acid alkyl esters, and acrylic acid alkyl esters in the presence of 50 to 85 parts by weight of a butadiene- or alkyl acrylate-based rubber, the sum of the graft and rubber components being 100 parts by weight.
