Abstract: Disclosed herein is a foamable composition comprising an olefin copolymer that comprises ethylene and an α-olefin; an unneutralized carboxylated olefin copolymer; a crosslinking agent; a blowing agent; and an activator; where a weight ratio of the activator to the unneutralized carboxylated olefin copolymer is greater than 0.3. Disclosed herein too is a method of manufacturing a foamable composition comprising blending together an olefin copolymer that comprises ethylene and an α-olefin; an unneutralized carboxylated olefin copolymer; a crosslinking agent; a blowing agent; and an activator to form the foamable composition; where a weight ratio of the activator to the unneutralized carboxylated olefin copolymer is greater than 0.3; heating the foamable composition to activate the blowing agent to form a foam; and crosslinking the foam.

Abstract: A process of adhering a foam structure to a rubber substrate is provided. The foam structure is composed of a first composition comprising a first ethylene-based polymer having a peak melting temperature TE1. A film composed of a second composition comprising a second ethylene-based polymer having a melt index≤10 g/10 min and a peak melting temperature TE2 is applied to the surface of the rubber substrate to form a rubber substrate/film configuration. A compression force is applied at a temperature Tv (38° C.≤TE2
