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.
A water borne polyurethane which is a urethane reaction product of a polyisocyanate, a neutralizing base and a polymeric acid functional polyol which is a polyol reaction product of (i) at least one polymer selected from the group consisting of polyester polyols, polyether polyols, polyetherester polyols, polybutadiene polyols, polycarbonate polyols, polyacrylic polyols, and hydroxy-terminated polyolefins;
A water borne polyurethane which is a urethane reaction product of a polyisocyanate and a polymeric acid functional polyol which is an esterification reaction product of (i) at least one first component selected from the group consisting of an aliphatic dicarboxylic acid, and a polyol;
A method of making a water borne ionomeric polyurethane, comprising the steps of:
