摘要：
A thermoplastic resin composition is provided containing (a) a polyester resin having a hydroxyl level of at least 45 meq/kg, (b) a polycarbonate resin, (c) a quencher and preferably (d) a graft copolymer containing a rubbery substrate and a rigid superstrate. The thermoplastic resin composition exhibits enhanced resistance to property degradation during molding and exhibits enhanced paint adhesion properties. The composition is useful for making painted articles such as automotive bumpers.
