Mo3249 LeA 26,479 A PROCESS FOR THE PRODUCTION OF PLASTICS BY THE POLYISOCYANATE POLYADDITION PROCESS AND CATALYSTS SUITABLE FOR THIS PROCESS The present invention is directed to a process for the production of polyurethanes using catalysts based on triamino(imino)phosphoranes corresponding to formulas I, II or III wherein R, R', R" and R"' represent hydrocarbon substituents and n and m may be the same or different and represent 0, 1 or 2. The present invention also relates to certain of the triamino(imino)phosphoranes used as catalysts. Le A 26 479
