H-1-NMR STUDY OF REACTION OF MELAMINE WITH OXIRANES

This work describes results of investigations relative to composition and structure of the initial products of the addition of oxiranes to m elamine analyzed by H-1-NMR spectrometry. The work Algebraic equations are shown that describe changes of contents in the functional groups of intermediate products in the function of the number of moles of oxi rane that were attached. Reactivity of individual function groups of i ntermediate products are also discussed. The structure of polyetherols with an s-triazine ring that forms in the reaction of melamine with o xiranes is proposed on the basis of these investigations. (C) 1995 Joh n Wiley & Sons, Inc.
