摘要: A polyurethane-urea composition is described that is highly resistant to textile fiber-dressings. The composition is a product from the reaction of an ester urethane prepolymer formed from the reaction of a diisocyanate and a hydroxy-terminated polyester of equivalent weight 400-1,000 in which the ratio of isocyanate functionality:hydroxy functionality is from 2.0:1 to 4.0:1; and an excess of water.
