ABSTRACT:
An amine catalyst for producing polyurethane comprising a compound of formula (I): ##STR1## wherein n is an integer from 0 to 3, and R.sub.1, R.sub.2, and R.sub.3 are each independently a C.sub.1-3 alkyl group. The amine catalyst has a secondary hydroxyl group in the molecule and is non-bleeding in the polyurethane resin and excellent in moldability. A process for producing a polyurethane foam by reacting a polyol with a polyisocyanate in the presence of the amine catalyst defined above and a foaming agent are also disclosed.
