Dynamic thermoplastic elastomer based on chlorosulfonated polyethylene

A new kind of dynamic thermoplastic elastomers based on chlorosulfonated polyethylene and lowdensity polyethylene, which combine the advantages of composites of polyolefin with nitrile rubber and of polyolefin with ethylene-propylene rubber and are free of their drawbacks, was developed. The composite undergoes self-cross-linking in the course of processing. The specific features of the structure of the composite, associated with the formation of an intermediate interfacial layer, were revealed. The materials exhibit high strength and are resistant to heat, frost, petroleum products, and ozone.
