    摘要: The invention includes an interlayer film and composition comprising a polymer composition obtainable from (a) at least one low crystallinity propylene polymer, and at least one (b) internal adhesion enhancer, (c) at least one clarity enhancer or (d), more preferably, both (b) and (c). The invention also includes a process of preparing a film comprising (a) supplying at least one first component, a low crystallinity propylene polymer, (b) supplying at least one second component, selected from at least one an internal adhesion enhancer, at least one clarity enhancer or a combination thereof; and, (d) admixing the first and second components and optional additives. Additionally, the invention includes a process of making a laminate comprising steps of (a) positioning at least one layer of the interlayer film directly adjacent to at least one layer of substrate (b) applying sufficient heat or other energy to result in softening of the interlayer directly adjacent the substrate with simultaneous application of sufficient pressure to press polymer into intimate contact with substrate. The invention also includes laminates and articles comprising the composition or film of the invention or a combination thereof.

    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.
