ABSTRACT:
A process for producing a polyurethane foam by reacting an organic polyisocyanate with an organic polyester polyol or polyether polyol in the presence of a catalytic amount of specific amine compounds of the formula: ##STR1## wherein R.sup.1 is a methyl or ethyl and R.sup.2 is hydrogen or methyl such that when R.sup.1 is methyl, R.sup.2 is methyl and when R.sup.1 is ethyl, R.sup.2 is hydrogen, X is an organic mono or dicarboxylic acid and n is an integer from 0 to 1.
