Abstract
A rapidly-crystallizing modified poly(ethylene terephthalate) contains an acrylic core/shell impact modifier, a small amount of a polycarbonate, and a small amount of a copolymer of ethylene with a vinyl or vinylidene monomer containing ester groups. Improved mold release and lessened plate-out are observed over other additive combinations.
