ABSTRACT:
Chlorinated polyvinyl chloride (CPVC) polymer alloys generally contain relatively large amounts of a flow enhancing polymer such as alpha-methyl styrene and a compatibilizing agent such as styrene acrylonitrile copolymer. The alloys are made from blends having a significant increase in processing stability, often more than double than CPVC compounds. Conventional salts can be utilized to co-stabilize the blends. Other improved physical properties of the alloys include dramatically reduced melt viscosities and good flexual modulus when compared to CPVC. Good impact resistance can be developed by the incorporation of impact modifiers such as acrylonitrile-butadiene-styrene copolymers. The smoothness of milled sheets made from the CPVC alloys is also significantly improved.
