摘要：The subject invention provides a thermoset elastomer comprising a crosslinkedpseudorandom or substantially random interpolymer of: (a) from 15 to 70 weightpercent of at least one &agr;- olefin, (b) from 30 to 70 weight percent of at least onevinylidene aromatic compound, and (c) from 0 to 15 weight percent of at least one diene.The subject invention further provides a thermoplastic vulcanizate comprising thethermoset elastomers of the invention as provided in a thermoplastic polyolefin matrix.The subject invention further provides processes for preparing the inventive thermosetelastomers and thermoplastic vulcanizates, as well as parts fabricated therefrom. Theinventive materials have a superior balance of properties, as compared to EPM and EPDMbased materials. The subject invention also pertains to foams and methods for theirpreparation.
