Abstract

Low-density crosslinked propylene polymer foams are prepared by mixing a propylene polymer with up to 20% of its weight of low molecular weight liquid polybutadiene(s) containing at least 35% by weight of 1,2-vinyl- polybutadiene and from 10 to 100% of its weight of EPDM rubber, EPM rubber or chlorinated polyethylene, together with a crosslinking or foaming agent, irradiating the mixture for crosslinking and then foaming it.
