ABSTRACT:
Thermoplastic compositions are prepared by blending an ethylene-hexene and/or an ethylene-butene copolymer resin, with a rubber and dynamically vulcanizing the rubber to form a heat-shrinkable dynamically vulcanized alloy of exceptionally low hardness, and great flexibility and elasticity. The preferred rubber is halogenated butyl rubber. Uncured rubber can be included in the composition.
