ABSTRACT OF THE DISCLOSURE The use of N-methoxypropylmorphine, N-butylmor- pholine and N,N'-dimethylpiperazine together as a catalyst system in an activator solution to give finer, more uniform cells to polyester-based polyurethane foams is described. While each of the amine catalysts has disadvantages when used alone in an activator solution, it was surprisingly discovered that together as a catalyst system none of the disadvantages were observed in the resulting polyurethane foam.
