Abstract
A method is provided for preparing polyurethane foams, which comprises contacting at least one organic isocyanate compound, at least one polyol, at least one blowing agent, and a tertiary amine catalyst composition. The catalyst composition has the general formula wherein R1, R2, and Y are, independently, an alkyl group having from one to three carbon atoms or —CH2CH2OH; Z is —CH2CH2OH; and n is an integer from 3 to 7, inclusive. Also provided is a method for catalyzing the reaction between at least one isocyanate compound and at least one active hydrogen-containing compound, such as a polyol and/or a blowing agent.
