More Information
Summary:A thermoplastic molding composition having good gloss and physical properties is disclosed. This composition contains in intimate admixture: a vinyl chloride polymer; a copolymer of a vinyl aromatic compound and an alpha , beta -unsaturated cyclic anhydride; a styrene-maleic anhydride copolymer having a number average molecular weight within the range of from about 1000 to about 8000; and an alkyl diphenyl phosphite. The copolymer of a vinyl aromatic compound and an alpha , beta -unsaturated cyclic anhydride can be rubber modified.
