STUDY OF REACTION BETWEEN N,N,N',N',N''-PENTAKIS(HYDROXYMETHYL)MELAMINE AND ETHYLENE OR PROPYLENE-OXIDE

The effects of the kind and amount of oxirane (propylene or ethylene o xide), the amount of triethylamine catalyst, and the temperature on th e reaction with N,N,N',N',N ''-pentakis (hydroxymethyl)melamine (PHMM) in DMSO solution were studied. The changes in the content of reactive groups in the reaction mixture and in the final product were analyzed . The oxirane addition was shown to be accompanied by the condensation of hydroxymethyl groups in the PHMM. Optimal conditions for the synth esis and the structural formula of the s-triazine ring containing poly etherols were established. (C) 1997 John Wiley & Sons, Inc.
