Abstract
Liquid thixotropic isocyanate-terminated prepolymers are prepared by the reaction of a polyarylene polyalkylene polyisocyanate or diphenylmethane diisocyanate with certain graft polyols. The resulting prepolymers are particularly useful in the preparation of polyurethane coating compositions.
