A composition comprising at least the following components: A) an olefin multi-block copolymer; and B) a silicone rubber that comprises pendant vinyl groups, and optionally comprises terminal vinyl groups.

Olefin multi-block copolymer / silicone rubber compositions and foams formed from the same

A waterborne polyurethane dispersion is provided. The waterborne polyurethane dispersion is prepared by using a tri-functionality polyether polyol as part of the polyols for forming the prepolymer and a hydrophilic amino siloxane co-chain extender, and can exhibit superior performance properties such as enhanced color fastness, improved low temperature stability, good anti-stickiness, bally flex resistance, anti-abrasion and mechanical properties. A laminated synthetic leather article prepared with said waterborne polyurethane dispersion as well the method for preparing the synthetic leather article are also provided.

A composition comprising at least the following: A) an olefin multi-block copolymer; B) a silicone rubber; C) a tackifier.

Olefin multi-block copolymer / silicone rubber / tackifier compositions and foams

The present disclosure provides a process. The process includes (i) forming a composition containing a peroxide-modified ethylene-based polymer selected from the group consisting of a peroxide-modified ethylene/a-olefin multi-block copolymer, a peroxide-modified low density polyethylene, and combinations thereof; (ii) contacting the composition with a blowing agent to form a foam composition; and (iii) forming foam beads comprising the foam composition. The present disclosure also provides a foam bead produced by said process.

Process for producing foam beads using a modified ethylene-based polymer

Disclosed herein is a foam composition comprising an olefin copolymer that comprises ethylene and an &#x3b1;-olefin or propylene and an &#x3b1;-olefin; an unneutralized carboxylated olefin copolymer; a crosslinking agent; and a blowing agent; where the foam composition is substantially free from neutralized carboxylated ethylene copolymer. Disclosed herein too is a method of manufacturing a foam composition comprising blending together an olefin copolymer that comprises ethylene and an &#x3b1;-olefin or propylene and an &#x3b1;-olefin; an unneutralized carboxylated olefin copolymer; a crosslinking agent; and a blowing agent to form the foam composition; where the foam composition is substantially free from neutralized carboxylated ethylene copolymer; heating the foam composition to activate the blowing agent to form a foam; and crosslinking the foam.

Blends for foams, foams manufactured therefrom and articles comprising the same
