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 comprising a compound having the following formula I:
whereR1 is hydrogen or a linear or branched C1-C4 alkyl or a C1-C4 hydroxyalkyl group;
R2 and R3 independently are hydrogen, hydroxy, a linear or branched C1-C4 alkyl or a linear or branched C1-C4 hydroxyalkyl group; and
R4 is a linear or branched C1-C10 hydroxyalkyl group.
