    摘要: 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 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. The subject invention also pertains to foams and methods for their preparation.

    摘要: A monomer compound has the formula (I): where each R1, R2, and R3 is independently H, F, C1-10 alkyl, fluoro-substituted C1-10 alkyl, C1-10 cycloalkyl, or fluoro-substituted C1-10 cycloalkyl, provided that at least one of R1, R2, or R3 is F; n is an integer of from 1 to 10, A is a halogenated or non-halogenated C2-30 olefin-containing polymerizable group, and G+ is an organic or inorganic cation. The monomer is the reaction product of a sultone precursor and the oxyanion of a hydroxy-containing halogenated or non-halogenated C2-30 olefin-containing compound. A polymer includes the monomer of formula (I).
