A solventless waterborne polyurethane emulsion is synthesized by prepolymerization. The effecting factors including the ratio of isocyanate content to hydroxyl group's (-NCO/-OH), the reaction temperature and the carboxyl group content (- COOH %) on target prepared emulsion's viscosity; particle diameter and the water absorption are experimentally… CONTINUE READING
