Abstract
Abstract A thermoplastic resin composition having excellent physical properties such as heat resistance and impact resistance and being improved in resistance to heat decomposition which comprises: (A) an unsaturated dicarboxylic acid anhydride polymer produced by polymerization of (a-1) at least one unsaturated dicarboxylic acid anhydride and (a-2) at least one of aromatic vinyl compounds, unsaturated nitrile compounds and unsaturated carboxylic acid esters in the presence or absence of (a-3) at least one rubbery material, (B) a polycarbonate resin, (C) a modified olefin polymer, and optionally (D) a rubber-reinforced resin produced by polymerizing (d-1) at least one of aromatic vinyl compounds, unsaturated nitrile compounds and unsaturated carboxylic acid esters in the presence of (d-2) a rubber polymer.
