    摘要： Certain tetrahydrocarbylphosphonium bicarbonate salts are produced by reacting a trihydrocarbyl(hydrocarbylcarboxymethyl)phosphonium hydroxide inner salt with water. For example, methyl tri-n-butylphosphonium bicarbonate salt was prepared in quantitative yields by heating tri-n-butylcarboxymethylphosphonium hydroxide inner salt in an aqueous methanol solution at 100.degree. C. for 3 hours.

    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.

    摘要： Ar-cyclic sulfonium arenethiol salts exemplified by the formula: ##STR1## may be converted to their corresponding zwitterion, exemplified by the formula: ##STR2## The latter polymerize very readily upon exposure to mild conditions of heat or radiative energy. The resultant polymers are water-insoluble resins useful as adhesives, coatings, films and the like. The zwitterions containing more than one arenesulfide and cyclic sulfonium group per molecule, crosslink upon exposure to heat to form thermoset resins.
