ABSTRACT:
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 at least one compound of the following formula; ##STR1## where R is hydrogen, c.sub.1 -c.sub.8 alkyl, c.sub.6 -c.sub.10 aryl or c.sub.7 -c.sub.10 aralkyl, and n is 0-3. The preferred catalyst consists essentially of of the compound when n is 0, namely 3-quinuclidinol.
