Abstract
Novel polyurethane-urea foams having superior tear and tensile strengths, elongation and load-bearing are prepared by reacting an alkylthio-substituted aromatic diamine in a mixture of polyols with an aromatic diisocyanate or aromatic diisocyanate prepolymer or mixtures thereof, having free NCO content of 0.1-50% by weight. These foams have good dynamic properties that make them attractive as cushioning materials.
