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.
可在水基体系中分散或溶解的聚酯组合物作为粘合剂、涂料、油漆等非常有价值。 水基溶剂体系的使用消除了通常与许多有机溶剂有关的回收和毒性问题。 本发明的聚酯组合物通过在其中加入有机磺酸单体的盐以及在很大程度上对这些聚酯进行羧基端接,增加了对水基体系的亲和力。 这些改性聚酯可用于的水基体系中除了水之外还含有醇。
