Froth and durable foam of dispersed olefin polymers, methods of making foam and articles prepared from same

摘要

A durable, open-cell foam comprising a) one or more copolymers or interpolymers of ethylene and/or 1-propene, with or without other monomers selected from C 4 to C 10 olefins, and which has an ethylene or 1-propene content from about 2-98 weigh percent, wherein the cell size of the majority of cells of the foam ranges between about 5 and about 1000 micrometers (microns).
