摘要

CONNECTION OF POLYVINYL CHLORIDE TO ESSENTIALLY POLYOLEFIN MATERIALS A connector (18) is provided capable of simultaneous sealing with improved strength to both polyvinyl chloride plastics and essentially polyolefin plastics. The formulation comprises certain block copolymers admixed with a small amount of polypropylene and optionally (ethylene-vinyl acetate).
