ABSTRACT:
Polymeric acid functional polyols are provided which are the reaction product of at least one hydroxyl-terminated polymer and a nonaromatic polyanhydride. Polymeric acid functional polyols are also provided which are the esterification reaction product of a first component which is at least one of an aliphatic dicarboxylic acid, a polyol and mixtures thereof and a second component which has at least two unhindered functional groups and at least one hindered carboxylic acid functional group. Methods of making such polymeric acid functional polyols by reacting a hydroxyl-terminated polymer and a nonaromatic dianhydride or by the esterification reaction of the first and second component described herein are also included in the invention. Further, hydrophilic polyurethane foams and water borne polyurethanes formed from the reaction of these polymeric acid functional polyols with polyisocyanates are also provided.
