  The invention pertains to tertiary amines used as catalysts for the preparation of polyurethane foams prepared via the catalytic reaction of a polyisocyanate with a polyol in the presence of blowing agents, etc. The tertiary amine catalysts are prepared by reacting an olefinic nitrile with aliphatic polyol having at least secondary hydroxyl functionality in a ratio less than stoichiometric for providing cyanoalkylated polyol having residual hydroxyl functionality. The resulting cyanoalkylated polyol then is reacted with a secondary amine under conditions for effective reductive alkylation. The tertiary amine catalysts, because of residual secondary hydroxyl functionality, provide for uniform dispersion within a polyurethane formulation; they provide for additional or extended pot life in polyurethane formulations at temperatures below reaction condition, and they are bound by reaction on cure.

  本发明涉及用作催化剂的叔胺，用于制备在发泡剂等存在下通过多异氰酸酯与多元醇的催化反应制备的聚氨酯泡沫。叔胺催化剂的制备方法是将烯烃腈与至少具有仲羟基官能团的脂肪族多元醇进行反应，反应比例小于化学计量比，以提供具有残余羟基官能团的氰烷基化多元醇。然后在有效还原烷基化的条件下，将得到的氰烷基化多元醇与仲胺反应。 由于仲羟基官能团的残留，叔胺催化剂可在聚氨酯配方中均匀分散；在低于反应条件的温度下，可延长聚氨酯配方的使用寿命，并通过固化反应对其进行约束。
