摘要： 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 and 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.

摘要翻译：作为用于形成从柔性至硬质泡沫的细胞聚氨酯聚合物形成的催化剂，是β-氨基羰基化合物，其中羰基以酰胺基或羧酸酯基团存在，β-氨基以二烷基氨基或N-吗啉代或N，N'-哌嗪基杂环核。在水 - 异氰酸酯反应的催化中有效，这些β-氨基酰胺和β-氨基酯特别有利于制造模制和自由升高的水吹柔性泡沫，包括高弹性和阻燃性，阻滞泡沫。 β-氨基羰基催化剂允许形成基本上没有与胺如N-乙基吗啉相关的气味的泡沫产品。考虑到这种非常理想的特性及其其它有益的性质，本发明的催化剂有利地用作高回弹性和其它泡沫制剂中N-乙基吗啉的直接置换。
