ABSTRACT:
Polyurethane foams having high resistance to abrasion, discoloration, and rinkage and having high densities are produced by reacting a polyether diol with a cycloaliphatic diisocyanate, or with a prepolymer of a polyether diol and a cycloaliphatic diisocyanate, and one or more curing agents in the presence of small proportions of water to serve as a blowing agent, a surfactant, and a catalyst.
