摘要:
Blends of elastomers of chlorinated or chlorosulfonated polyethylene and ultra high molecular weight, i.e. at least one million, when cured with conventional curing systems for the chlorinated or chlorosulfonated polyethylene have higher tear strengths at temperatures of about 150.degree. C. than do the unblended elastomers. The amount of polyethylene in the blend is 5 to 50 parts by weight per 100 parts by weight of elastomer. The blend, thus produced has a modulus (M.sub.100) of greater than 1000 psi prior to curing.
