摘要: Compounds of formulas I and II are heat-activated catalysts used in making polyurethanes. ##STR1## wherein R, R.sub.1, and R.sub.2 are each independently H, hydrocarbyl or an inertly-substituted hydrocarbyl; R.sub.3 and R.sub.4 are each independently hydrocarbyl or an inertly-substituted hydrocarbyl; and X is an anion. Upon heating, Compounds I and II catalyze the reaction and may release gaseous by-products which cause the resulting polyurethane compound to foam. For example, the catalyst, t-butyl imidazole-N-carboxylate, when heated to 120.degree. C., catalyzes the reaction between a polyol and a polyisocyanate to give a foamed polyurethane which cured in 16 minutes.
