Thermoplastic olefin compositions of epdm rubber and ethylene copolymer resin.

摘要

Heat shrinkable thermoplastic compositions are prepared by blending an ethylene copolymer resin with an EPDM rubber and dynamically vulcanizing the rubber. The ethylene copolymer resin is a copolymer of ethylene with an alkyl ester of an alpha, beta monoethylenically unsaturated monocarboxylic acid as well as copolymers of ethylene with the acid per se. The preferred copolymer is ethylene-vinylacetate copolymer. Uncured rubber can be included in the composition.
