Abstract
Compositions of a polyvinyl chloride resin, a polyolefin which is the metallocene-catalyzed reaction product of ethylene and an alpha-olefin monomer, and a component selected from the group consisting of chlorinated polyethylene, polycaprolactone, and combinations thereof are disclosed. The compositions are essentially free of liquid plasticizers, and prossess good mechanical properties of tensile strength, elongation, and a low brittle point, even after being subjected to high heat for an extended period of time.
