BETA-AMINO CARBONYL CATALYSTS FOR POLYURETHANE PREPARATION ABSTRACT OF THE DISCLOSURE Provided as catalysts for the formation of cellular urethane polymers ranging from flexible to rigid foams, are beta-amino carbonyl compounds wherein carbonyl is present as an amido or carboxylic acid ester group ant the beta-amino group is present as dialkylamino or an N- morpholino or N,N'-piperazino heterocyclic nucleus. Effective in the catalysis of the water isocyanate reaction, these beta-amino amides and beta-amino esters are used with particular advantage in the manufacture of water-blown flexible foams, both molded and free-rise, including high-resilience and flame-retarded foam. The beta-amino carbonyl catalysts allow for the formation of foam products essentially free of the odor associated with amines such as N- ethylmorpholine. In view of this highly desirable characteristic and their other beneficial properties, the catalysts of the invention are advantageously employed as direct replacements for N-ethylmorpholine in high-resilience and other foam formulations.
