摘要：
Water-soluble polyurethanes prepared by reacting a polyisocyanate and a polyalkylene oxide polyol at a molar ratio sufficient to form an isocyanate-terminated polymer, and reacting the isocyanate-terminated polymer with an epoxy alcohol to form a water-soluble, epoxy-terminated polyurethane, are disclosed. Also disclosed are aqueous fiber sizing compositions including the water-soluble polyurethanes described.
