Title:
BLENDS FOR FOAMS, FOAMS MANUFACTURED THEREFROM AND ARTICLES COMPRISING THE SAME
Document Type and Number:
WIPO Patent Application WO/2018/058422
Kind Code:
A1
Abstract:
Disclosed herein is a foam composition comprising an olefin copolymer that comprises ethylene and an α-olefin or propylene and an α-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 α-olefin or propylene and an α-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.
