Amine-boron adducts as reduced odor catalyst compositions for the production of polyurethanes

摘要

An amine-boron composition for catalyzing the urethane reaction, particularly in preparing a polyurethane foam, consisting essentially of the addition product of a tertiary amine and a boron compound of the formula RnB(OH)3-n where n=0 or 1, and R=C1-C8 alkyl, C5-C8 cycloalkyl or C6-C10 aryl. Preferred catalysts are prepared by mixing triethylenediamine with boric acid.
