ABSTRACT:
The present invention relates to ionic and nonionic polyamide modified polyurethane polymers for use in coating compositions, a method for forming the polymer and coating compositions containing these polymers. The polyamide modified polyurethane polymers of the present invention include polyamide formed from aromatic, aliphatic, or cycloaliphatic anhydrides or diacid halides and an amine containing compound such as amino alcohol, amino thiol, diamine or mixtures thereof, wherein the reactive terminii of the polyamide ere substituted by hydroxyl or thiol functional groups, together with a chain extending alcohol and diisocyanate functional monomer.
