Producing isocyanate prepolymers useful for producing adhesives and sealants comprises reacting diisocyanates with a compound with at least two isocyanate-reactive groups using dibutyltin dineodecanoate as catalyst

摘要

Producing isocyanate prepolymers by reacting diisocyanates with a substoichiometric amount of a compound (I) with at least two isocyanate-reactive groups comprises using dibutyltin dineodecanoate as catalyst. An independent claim is also included for isocyanate prepolymers produced as above.
