ABSTRACT:
A composition of matter comprising a blend of CPVC having a chlorine content of between about 60% and 65% by weight and styrene-acrylonitrile copolymer having an acrylonitrile content of between about 15% and 25% by weight. The composition of matter displays substantially single, homogeneous phase behavior with the CPVC and styrene-acrylonitrile copolymer being substantially or completely miscible. Blending of CPVC and styrene-acrylonitrile copolymer provides a resulting blended polymeric material having enhanced temperature and durability properties. Melt processability of CPVC polymeric material may be enhanced by the inclusion of styrene-acrylonitrile copolymer to form the blends.
