Abstract:

This disclosure pertains to novel polyvinyl chloride compositions containing polyvinyl chloride resins, polycarbonate resins and copolyester resins. More particularly, the present disclosure pertains to polyvinyl chloride compositions including admixtures of polycarbonates and high glass transition temperature (T.sub.g) copolyesters to increase the T.sub.g and the heat distortion temperature under load (HDTUL) of the polyvinyl chloride compositions.
