NCO-FUNCTIONAL PREPOLYMER MADE OF DICYCLOHEXYL METHANE DIISOCYANATE, ISOPHORONE DIISOCYANATE, AND POLYETHER POLYOLS, HAVING A REDUCED TENDENCY TO CRYSTALLIZATION

摘要

The invention relates to NCO-functional prepolymers prepared from dicyclohexylmethane diisocyanate (H12MDI hereinafter) and polyether polyols, with a reduced tendency to crystallization, a fraction of the H12MDI being blended with further monomeric isophorone diisocyanate (IPDI hereinafter), so making it possible to reduce or prevent entirely the tendency to crystallization, and also to the preparation and use.
