Abstract

Abstract Water insoluble polycaprolactone-epoxide adducts are produced comprising the reaction product of a polycaprolactone polyol, a diepoxide and an anhydride of a polycarboxylic acid. The polycaprolactone polyol reacted with the diepoxide and the anhydride of the polycarboxylic acid has at least two hydroxyl groups in the molecule, a hydroxyl number of from about 15 to about 600 and an average molecular weight of from about 290 to about 6,000. The carboxylic acid anhydride has at least one intramolecular carboxylic anhydride group. These water insoluble polycaprolactone-epoxide adducts on reaction with an inorganic or organic base produce water soluble, carboxyl modifier polycarprolactone-epoxide oligomer addition reaction products which are eminently suitable for the production of aqueous coatings compositions. Exceptionally good coatings compositions are obtained when a crosslinker is present in the coating composition.
