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 a compound having the following formula I:
where
R1 is hydrogen or a C1-C4 linear or branched alkyl, hydroxyalkyl or aminoalkyl group;
R2 is hydrogen or a C1-C6 linear or branched alkyl, hydroxyalkyl or aminoalkyl group; and
R3 and R4 are independently hydrogen or a C1-C10 linear or branched alkyl, hydroxyalkyl or aminoalkyl group which may contain ether functionality.

其中
R1 是氢或 C1-C4 直链或支链烷基、羟基烷基或氨基烷基;
R2 是氢或 C1-C6 直链或支链烷基、羟基烷基或氨基烷基;和
R3 和 R4 独立地为氢或 C1-C10 直链或支链烷基、羟基烷基或氨基烷基,可含有醚官能团。
