ABSTRACT:
Novel high resilience (HR) urethane foams are prepared from tolylene diisocyanate and novel polymer/polyol compositions made with acrylonitrile and vinylidene chloride monomers. The acrylonitrile:vinylidene chloride-polymer/polyol compositions enhance the load-bearing properties and decrease the flammability of HR foams made with them.
