Abstract
Water dispersible oil-modified polyesters and oil-free polyesters are formed by the reaction of aromatic dicarboxylic acids, aliphatic dicarboxylic acids and polyols to form the polyester. In oil-free polyesters, oils of the respective fatty acids are excluded but the other reactants are similar to those employed in the preparation of oil-modified polyesters.
