    摘要: The present invention consists of a method for the preparation of an anionic water dispersible polyurethane(PU), which has excellent adhesive properties. The preparation method involves the formation of prepolymer from polyisocyanates and an active hydrogen containing compound such as polyols, followed by chain extension with aliphatic diols or diamines, and finally by chain extension with N-(2-aminoalkyl-2-aminoethoxylate ethane sulfonate and dispersion of the reaction product by deionized water to obtain water-borne polyurethane adhesive.
