Vulcanization of hose composites protected with thermoplastic jackets

Claim 1

A process for curing an elastomeric tubular article, comprising the steps of: applying a recyclable thermoplastic jacket around the elastomer tubular article, said thermoplastic jacket being a material selected from the group consisting of polymethylpentane, high molecular weight polyethylene, fluoronated ethylene propylene copolymer, segmented polyesters, polyphenylsulfide, and a blend of a material having from about 25 to about 100 percent by weight of a thermoplastic polyolefin resin and from about 75 percent to about 0 or 1 percent by weight of a vulcanized monoolefin copolymer rubber based upon the total weight of said resin and said rubber, and from about 0 to about 300 parts by weight of oil based upon the total weight of said resin and said rubber, provided that when the amount of resin is greater than 75 percent by weight, said oil must be present in an amount sufficient to satisfy the equation (W o +W r )/W p is equal to or greater than 0.33 wherein W o is the weight of oil, W r is the weight of rubber, and W p is the weight of resin, wherein said polyolefin resin is a polymer of one or more olefins having from 2 to 8 carbon atoms, and wherein said monoolefin copolymer rubber is a polymer made from two or more alpha monoolefins having the formula CH 2 ═CHR in which R is hydrogen or an alkyl of from about 1 to 12 carbon atoms, and from about 0 to about 10 percent by weight based upon the total weight of said alpha monoolefins of a diene having from 5 to 12 carbon atoms; compacting and curing said elastomeric tubular article; and removing said thermoplastic jacket from said tubular article.
