The study of the kinetics of addition and condensation in the (hydroxy
methyl)melamine-oxirane system in DMSO solution and in the presence of
triethylamine catalyst is described. The mechanisms of the reactions
are presented. The kinetics parameters have been used to optimize the
conditions of preparation of the s-triazine ring containing polyethero
ls from pentakis(hydroxymethyl)melamine and ethylene or propylene oxid
