Abstract
Dispersion-stable polymeric acid functional polyols and dispersions of such materials, a method for improving the long term storage dispersibility and hydrolytic resistance of an acid functional polyol and a method for making a water-borne polyurethane, as well as personal care and industrial lubricants, using such improved acid functional polymeric polyols are provided. The polymeric acid functional polyols are reaction products of reaction mixtures including a base polyol having at least one of a terminal secondary and/or tertiary hydroxyl group and an aromatic anhydride.
