ABSTRACT:
Cellular urethane polymers are provided by effecting the reaction of an organic polyol reactant comprising a polyether polyol and an organic polyisocyanate reactant in the presence of a blowing agent and a catalyst system comprising an N,N-dimethylaminoalkoxypropionitrile. The said N,N-dimethylaminoalkoxypropionitriles are versatile, low odor catalysts and are useful in forming cellular urethane polymers ranging from all water-blown flexible polyether foam to all fluorocarbon-blown rigid foam products. Especially preferred for use in the practice of the invention are 3-(2-dimethylaminoethoxy)propionitrile and 3-[2-(2-dimethylaminoethoxy)ethoxy]propionitrile either as such or in combination with other catalysts including other tertiary-amine components and/or organic compounds of tin. Also provided are blended catalyst systems comprising said dimethylaminoalkoxypropionitriles.
