ABSTRACT:
Polyester compositions which are dispersible or soluble in water based systems can be very valuable as adhesives, coatings, paints, and the like. The use of water based solvent systems eliminates recovery and toxicity problems normally related with many organic solvents. The polyester compositions of this invention have an increased affinity for water based systems by the incorporation therein salts of organic sulfonic acid monomers and by carboxyl terminating these polyesters to a very substantial degree. The water based systems in which these modified polyesters are useful contain an alcohol in addition to water.
