OLEFIN POLYMER FOAMS

摘要

Olefin polymer foams having improved cell structures and relatively smooth outer surfaces produced by foaming a composition containing a thermoplastic olefin polymer, p,p'-oxybis-benzene sulfonyl hydrazide, a monomeric acrylate ester of a polyhydric compound and an organic peroxide. These foams can be formed into shaped articles of desired configuration by conventional thermoforming molding techniques.
