In this report, half-esterification between these pendent hydroxyl groups of hydroxyl-PU and maleic anhydride could lead to new pendent groups, carboxylic groups. These highly polar carboxylic groups in the side chain of PU could play the role of internal emulsifier. They had self-dissociation ability in the water or were neutralized first by appropriate amount of base. Then, PU bearing carboxylic group could dispersed steadily in the water, named aqueous-based polyurethane dispersion.
