Abstract
The impact strength of unsubstituted aromatic polycarbonate resins is improved by inclusion of certain gel materials with the resin before molding. The gel additive can be derived from a rubber modified alkenyl aromatic resin, is in the form of rubbery particles comprised of rubber, rubber grafted alkenyl aromatic resin and occluded alkenyl aromatic resin, and is substantially free of all but trace amounts of soluble alkenyl aromatic homopolymer.
