Abstract:
A filled polymer composition comprises (i) an ethylene/a-olefin interpolymer, and (ii) a filler. The ethylene/a-olefm 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 present invention is a crosslinkable, expandable polymeric composition comprising a free-radical crosslinkable polymer, a free-radical inducing species, a crosslinking-profile modifier, and a blowing agent. Preferably, the free-radical inducing species is a low temperature free-radical inducing species.
Abstract:

The compositions comprise at least one ethylene/a-olefin interpolymer, wherein the ethylene/a-olefin interpolymer may have, for example, a Mw/Mn from about 1.7 to about 3.5, at least one melting point, Tm, in degrees Celsius, and a density, d, in grams/cubic centimeter, wherein the numerical values of Tm and d correspond to the relationship: Tm > -2002.9 + 4538.5(d) - 2422.2(d)2.
Abstract:
Polymer blends comprises 1) at least one ethylene/a-olefin interpolymer and 2) at least one polyolefin, or at least one styrenic block copolymer, or a combination thereof. Such polyolefins include, but are not limited to, high melt strength high density polyethylene and high melt strength polypropylene. The ethylene/a-olefin interpolymers are random block copolymers comprising at least a hard block and at least a soft block. The polyolefins can be homopolymers or interpolymers. The resulting polymer blends can be used to make flexible molded articles.
