Abstract
A method for preparing a polyurethane foam which comprises reacting an organic polyisocyanate and a polyol in the presence of a blowing agent, cell stabilizer and a catalyst composition consisting essentially of at least one of the permethylated mono- and dialkylene oxide adducts of tris(2-aminoethyl)amine of structures I, II and III, or any combination thereof ##STR1## wherein R is hydrogen, a C.sub.1 -C.sub.4 alkyl, C.sub.6 -C.sub.8 aryl, or C.sub.7 -C.sub.9 aralkyl group.
