(57) [Summary] [Object] To provide a heat-resistant resin composition comprising a specific maleimide-type copolymer having good compatibility with a polyester resin, which is excellent in heat resistance, impact resistance and moldability. [Structure] 30 to 79.99% by weight of at least one monomer unit (A) selected from the group consisting of aromatic vinyl monomers and methacrylic acid ester monomers, and maleimide monomer units ( B) 20 to 60% by weight, epoxy group-containing monomer unit (C) 0.01 to 10% by weight, and other vinyl-based monomer unit (D) copolymerizable with these monomers Maleimide-based copolymer (0 to 20% by weight (however, the total of these monomer structural units (A), (B), (C) and (D) is 100% by weight)) A heat-resistant resin composition containing 1) and an aromatic polyester resin (2). |
