Abstract: The present invention is directed to novel isocyanate-terminated prepolymers of carboxylic acid grafted polyethers, salts of these prepolymers and fully reacted polymers formed therefrom. More specifically, the present invention relates to reacting an ethylenically unsaturated mono-carboxylic acid with a polyether in the presence of a free radical initiator to form a graft copolymer. Acid-containing isocyanate- terminated prepolymers can then be formed by reacting the graft copolymer with an isocyanate. Salt-containing isocyanate-terminated prepolymers are prepared through the reaction between the acid-containing prepolymer and a base. Finally, polymers are formed by curing either of these isocyanate-terminated prepolymers with an isocyanate reactive material.
Abstract translation: 本发明涉及新颖的羧酸接枝聚醚的异氰酸酯封端的预聚物，这些预聚物的盐和由其形成的完全反应的聚合物。 更具体地，本发明涉及在自由基引发剂的存在下使烯属不饱和单羧酸与聚醚反应以形成接枝共聚物。 然后可以通过使接枝共聚物与异氰酸酯反应形成含酸异氰酸酯封端的预聚物。 通过含酸预聚物和碱之间的反应制备含盐异氰酸酯封端的预聚物。 最后，通过用异氰酸酯反应性材料固化这些异氰酸酯封端的预聚物中的任一种来形成聚合物。
