  • Publication number: 20060199030
    Abstract: The present invention relates to film layers and compositions having improved hot tack properties. The compositions comprise at least one ethylene/?-olefin interpolymer, wherein the ethylene/?-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.

  • Publication number: 20060189759
    Abstract: A novel flooring composition was developed based on a blend comprising: a) an elastomer; b) a random propylene/alpha-olefin copolymer; c) a cross linking agent; and optionally d) a melt strength enhancing polymer. This composition achieves a unique balance of properties, exhibiting often-conflicting performance requirements. These include low gloss and excellent pattern duplication in embossing, low modulus, minimal odor, excellent grain acceptance and abrasion resistance, while remaining thermoformable and maintaining minimal shift in viscosity during recycle.

  • Patent number: 6818163
    Abstract: An improved process for making a structural foamed polymer, a multilayer polymer film, sheet or tube, a pultrusion polymer profile, a compression molded extruded fiber reinforced polymer pre-form, a strand foamed polymer and a SCORIM formed polymer article. The improvement includes the step of dispersing a multi-layered silicate material with the polymer so that the polymer has dispersed therein single layers of silicate material, double layers of silicate material, triple layers of silicate material, four layers of silicate material, five layers of silicate material and more than five layers of silicate material, the volume percent of the one, two, three, four and five layers of silicate material greater than the volume percent of the more then five layers of silicate material. In each of the above embodiments an important benefit of the instant invention is the orientation of the plane of the layers of silicate material.
