Abstract
This work is the second report on the system (hydroxymethyl)melamine ( HMM)-oxiranes reacting in non-aqueous media (DMSO) in the presence of triethylamine catalyst. Both a kinetic model and mechanism of condensa tion of hydroxymethyl groups have been proposed. The condensation is c atalysed by alcoholane anions formed in the addition step of HMM to et hylene or propylene oxide. No condensation has been found to take plac e during addition of HMM to glycerin epichlorohydrin (ECH). Oxirane ri ng in ECH is reformed instead at the expense of catalyst deactivation.
