ABSTRACT:
A polyblend which has high heat distortion temperature and high impact strength is produced from 80 to 20 percent by weight of vinyl chloride resins, which comprise 90 to 30 percent by weight of a rubber-modified vinyl chloride resin and 10 to 70 percent by weight of a vinyl chloride resin that is not rubber-modified; and 20 to 80 percent by weight of a polymer of a vinyl aromatic monomer such as styrene, an unsaturated dicarboxylic acid anhydride, such as maleic anhydride, and an optional third monomer such as methyl methacrylate or acrylonitrile, which polymer may be a rubber-modified polymer.
