摘要

A plastic composition which may be molded into a connector which is capable of simultaneously sealing to both polyvinyl chloride plastics and polyolefin plastics. The plastic composition comprises from 50 to 75 percent by weight of an essentially polyolefin material which is sealingly compatible with the polyolefin plastic to which the composition is intended to be sealed, and from 25 to 50 percent by weight of a flexible block copolymer of covalently bonded polybutylene terephthalate units and poly(1,4-butylene) oxide units.
