Heat-resistant blends of polypropylene, conjugated diene/monovinylarene rubbery block copolymers, with an in-situ cured polychloroprene

摘要

The loss in tensile of a polypropylene blend with a conjugated diene/monovinylarene rubbery block copolymer can be prevented by including in the blend an effective amount of a polychloroprene, followed by curing the composition with a curative which cures substantially only the polychloroprene component.
