Abstract
A foamable composition comprises at least about 50 wt % of a copolymer of ethylene and alkyl (meth)acrylate having a broad chemical composition distribution (CCD), and having a melt index between about 7 and about 30; about 2 to about 40 wt % of a polyolefin having a carboxylic acid or carboxylic acid anhydride functionality; about 1 to about 10 wt % of one or more foaming agents; and about 1 to about 5 wt % of one or more crosslinking agents. This foamable composition combines ease of processing with good foaming characteristics while avoiding unwanted characteristics, such as fogging.
