Abstract

Method of preparing water-dispersing polyurethane comprising: placing polyols and polyisocyanate in a 0-70 weight percent of diluent to form NCO-terminated urethane prepolymer; reacting compound with hydroxy group and CH2=CH-COO- or CH2=C(CH3)-COO-group with urethane prepolymer to form aminoformate prepolymer; adding primary or secondary polyatomic amines into the aminoformate prepolymer to form polyurethane containing amino group.
