Hydroxy-functional triamine catalyst compositions for polyurethane production

摘要

A method for preparing a polyurethane foam which comprises reacting an organic polyisocyanate and a polyol in the presence of a blowing agent, a cell stabilizer and a catalyst composition consisting essentially of 0-50 mole % compound I and 50-100 mole % compound II: <IMAGE> I <IMAGE> II wherein R is hydrogen, a C1-C4 alkly, C6-C8 aryl, or C7-C9 aralkyl group; and n is 2 to 8.
