Abstract
A polycarbonate blend composition comprising 95-5 wt % of a polycarbonate resin, 5-95% of an ABS resin and 0-01-5 parts per hundred of a heat stabilizer (relative to the combined resin weight). The heat stabilizers are selected from benzothiazoles of formula: ##STR1## wherein R is selected from hydrogen, alkyl, aryl and benzothiazolyl; benzimidazole compounds of formula: ##STR2## wherein R is selected from hydrogen, alkyl, aryl and benzimidazolyl; hydrazine compound of formula: ##STR3## wherein R is alkyl, and cation exchange materials selected from metal salts of silicaluminate zeolites, metal salts of triphosphates and cation exchange resins. These poly blend composition display improved impact resistance.
