摘要
An expandable composition of a solid synthetic vulcanizable elastomer of ethylene/higher alpha-olefin/nonconjugated diene copolymer or polychloroprene, a blowing agent, and a curing agent for the elastomer, said composition containing from about 5-25% based on the weight of total polymer of an ionomer resin which is an ethylene polymer containing at least about 50 mole percent ethylene and bearing from about 0.2-25 mole percent acid functional groups that are at least about 50% neutralized by metal ions.
