Abstract: A foamable composition comprising at least an olefin block copolymer, an olefin copolymer, an oil, a blowing agent and a crosslinking agent is provided. The olefin block copolymer has a Mw/Mn from 1.7 to 3.5, and at least one melting point, Tm, in degrees Celsius, and a density, d, in gram/cubic centimeter, wherein the numerical values of Tm and d correspond to the relationship: Tm>?2002.9+4538.5(d)?2422.2(d)2. Foams, laminates, articles and wetsuits made from the foams are also provided.

Abstract: A filled polymer composition comprises (i) an ethylene/?-olefin interpolymer, and (ii) a filler. The ethylene/?-olefin interpolymer is a block copolymer having at least a hard block and at least a soft block. The soft block comprises a higher amount of comonomers than the hard block. The block interpolymer has a number of unique characteristics disclosed here. The filled polymer compositions provided herein, in certain embodiments, have relatively higher heat resistance and improved noise, vibration and harshness properties and can be used in automotive floorings, roofings, wire and cable coating applications.

Abstract: The subject invention is directed to a rheology-modified ethylene polymer having less than 0.5 weight percent gel, a composition distribution breadth index (CDBI) greater than 50 percent, and a molecular weight distribution (Mw/Mn) of less than 4.0, which is characterized as having improved rheological performance and/or melt strength attributes relative to the unmodified polymer. The subject invention is further directed to polymer blends which comprise the rheology-modified polymers, and to a process for preparing the rheology-modified polymers.

Abstract: Formulated compositions having good uncured ("green") and cured physical properties are disclosed. The compositions comprise at least one substantially linear ethylene/C.sub.3 -C.sub.20 .alpha.-olefin copolymer, or alternately, at least one linear ethylene/C.sub.5 -C.sub.20 .alpha.-olefin copolymer. The compositions are easily molded and have particular utility in making wire and cable coatings.

Abstract: Substantially linear ethylene polymers, e.g., polyethylenes prepared by constrained geometry catalysis (substantially linear ethylene), which are grafted with one or more unsaturated organic compounds containing both ethylenic unsaturation and a carbonyl group, e.g., maleic anhydride, exhibit desirable adhesive properties. These graft-modified substantially linear ethylene polymers also impart desirable compatibility and impact properties to various thermoplastic polymer blends.
