Abstract
Abstract Disclosed are linear, water-dissipatable polyesters and polyesteramides derived from at least one dicarboxylic acid, at least one glycol, and at least one polycarboxylic acid or polyhydric alcohol which contains a sulfonic acid salt moiety derived from a nitrogen-containing base having an ionization constant in water at 25 DEG C. of 10-3 to 10-10. The polyesters may also contain an unsaturated acid and a difunctional hydroxycarboxylic acid, an aminocarboxylic acid or a diamine. Such polymers are especially useful as adhesives, coatings, films and the like.
