Abstract: A hot melt adhesive composition comprising a) from about 5 wt-% to about 50 wt-% of at least one homogeneous linear or substantially linear ethylene/alpha-olefin interpolymer characterized as having a density from 0.850 to 0.965 g/cm3; b) from about 1 wt-% to about 40 wt-% of at least one block copolymer; and c) from about 10 wt-% to about 75 wt-% of at least one tackifying resin wherein said adhesive does not fail cohesively.

Abstract: The present inventors have discovered that an easily measured property, namely complex viscosity, directly relates to physical film compatibility and have further identified a class of polyolefin materials, which are particularly amenable to exhibiting such properties. It is important to note that this discovery assumes that the film material is first chemically compatible with the thermoplastic composition to be packaged. The invention is particularly useful for low viscosity thermoplastic compositions having a Brookfield viscosity of less than about 10,000 cPs at 350° F., such as pressure sensitive hot melt adhesive compositions which are typically applied by melting the packaged adhesive composition in a melt tank wherein the melt tank lacks an active mixing means.

Abstract: Bitumens can be blended with interpolymers prepared from least one olefin and at least one vinyl or vinylidene aromatic monomer and, optionally, at least one diene. The interpolymers prepared from monomers containing a diene are new compositions of matter. When the interpolymers prepared from monomers containing a diene are blended with a bitumen, the blends are crosslinkable.

Abstract: The present invention relates to a foamable composition comprising a low viscosity thermoplastic composition comprising at least one ethylene/.alpha.-olefin. The foamable composition may comprise a single ethylene/.alpha.-olefin or a blend of such. Optionally, the foamable composition may further comprise at least one diluent including waxes, plasticizers such as oil, tackifying resin, and mixtures thereof. The present invention also relates to a method of foaming such compositions and articles constructed therefrom. More specifically, the present invention relates to foamable thermoplastic compositions having particular utility as cabinet sealant and as foam layers in disposable articles such as disposable diapers, incontinent devices, medical devices such as bandages and dressings, as well as a variety of other uses.

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 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.
