Abstract

A impact resistant polycarbonate composition comprises an elastomer-modified graft copolymer prepared by an emulsion process in which a composition comprising the elastomer-modified graft copolymer is subjected to treatment with acid to adjust the pH to about 3.0 to about 6.8, following by coagulation of the elastomer-modified graft copolymer and admixture with an aromatic polycarbonate.
