Abstract: Catalysts having the following formula have been found to have unexpectedly high activity for the production of polyurethane and polyisocyanate resins: ##STR1## where: R, R.sub.1 and R.sub.2 are alkyls having 1 to 4 carbon atoms,R.sub.3 and R.sub.4 are independently selected from the group consisting of H, alkyls having 1 to 12 carbon atoms and aryls and aralkyls having 6 to 18 carbon atoms, andR.sub.5 is selected from the group consisting of H, an alkyl having 1 to 2 carbon atoms and an aryl and an aralkyl having 6 to 15 carbon atoms.

Abstract: Polymerization and condensation reactions of organic isocyanates are catalytically promoted by the use of N-hydroxyalkyl quaternary ammonium carbonylate salts, particularly in the production of polyisocyanurates and polyurethanes. Among the exemplary preferred catalysts are N-hydroxypropyl trimethyl ammonium salts of carboxylic acids such as those of formic and acetic acids and of fatty acids such as hexanoic and octanoic acids and the like.

Abstract: Isocyanate reactions, such as their condensation with polyols to form polyurethanes and their polymerization to polyisocyanurates, are promoted by certain hydroxyalkyl tertiary amine catalysts corresponding to the formula ##STR1## wherein Y = CH.sub.3 or ZZ = --ch.sub.2.ch.sub.

Abstract: Catalysts having the following formula, prepared in the absence of water, are stable to heat and storage and show high activity in reactions involving organic isocyanates, such as in the production of polyurethane and polyisocyanurate resins: ##EQU1## wherein: A is a mono- or bicyclic tertiary amine having at least 4 carbon atoms in an azine ring,R.sup.1 is H or an alkyl group of 1 to 10 carbon atoms,R.sup.2 is H or an alkyl or aryl group of 1 to 10 carbon atoms, and.phi. is a phenyl group, which may be further substituted by one or more hydroxyl or alkyl groups.Typical compounds, for example, are those corresponding to the formula ##EQU2## wherein: R is H or methyl.

Abstract: Catalysts having the following formula have been found to have unexpectedly high activity for the production of polyurethane and polyisocyanate resins: ##EQU1## where: R, R.sub.1 and R.sub.2 are alkyls having one to four carbon atoms,R.sub.3 and R.sub.4 are independently selected from the group consisting of H, alkyls having one to 12 carbon atoms and aryls and aralkyls having six to 18 carbon atoms, andR.sub.5 is selected from the group consisting of H, an alkyl having one to two carbon atoms and an aryl and an aralkyl having six to 15 carbon atoms.
