Abstract

See full text

A thermoplastic resin composition contains a polycarbonate resin, a mass polymerized rubber modified graft copolymer that contains a discontinuous rubber phase dispersed in a continuous rigid thermoplastic phase, wherein at least a portion of the rigid thermoplastic phase is chemically grafted to the rubber and exhibits good processability, including a high melt flow rate, good physical properties, including good impact resistance, and improved resistance to edge cracking and to environmental stress cracking.
