Polyvinyl chloride thermoplastic blend compositions having improved glass transition tempratures

摘要

This patent relates to thermoplastic blend compositions having improved stiffness and increased glass transition temperature, wherein a major portion of polar thermoplastic resin is compounded with a minor portion of a neutralized sulfonated polymer. The neutralized sulfonated polymers of the present invention included sulfonated polystyrene butadiene copolymers, sulfonated butyl rubber, sulfonated EPDM and other sulfonated elastomeric polymers. The thermoplastic polar resins having a halogen-carbon bond include polyvinyl chloride.
