Abstract
A preferred rigid thermoplastic resin composition having high impact strength and resistance to thermal distortion includes a vinyl chloride resin/polycarbonate alloy and at least 3 parts by weight of butadiene-modified acrylic per 100 parts by weight of the alloy. A particularly preferred thermoplastic resin composition includes the alloy and both butadiene-modified acrylic and ethylene-vinyl acetate copolymer.
