Abstract: The subject invention provides a thermoset elastomer comprising a crosslinked pseudorandom or substantially random interpolymer of: (a) from 15 to 70 weight percent of at least one alpha -olefin, (b) from 30 to 70 weight percent of at least one vinylidene aromatic compound, and (c) from 0 to 15 weight percent of at least one diene. The subject invention further provides provides a thermoplastic vulcanizate comprising the thermoset elastomers of the invention as provided in a thermoplastic polyolefin matrix. The subject invention further provides processes for preparing the inventive thermoset elastomers and thermoplastic vulcanizates, as well as parts fabricated therefrom. The inventive materials have a superior balance of properties, as compared to EPM and EPDM based materials.

Abstract: Formulated compositions having good uncured ("green") and cured physical properties are disclosed. The compositions comprise at least one substantially linear ethylene/C3-C20 (alpha)-olefin copolymer, or alternately, at least one linear ethylene/C5-C20 (alpha)-olefin copolymer. The compositions are easily molded and have particular utility in making wire and cable coatings.
