NEW MELAMINE RESINS - I - SYNTHESIS OF REACTIVE SOLVENTS FOR MELAMINE

Some results are presented on the studies of reactive solvents for mel amine obtained from acetone and formaldehyde in the presence of potass ium bicarbonate or triethylamine as catalysts. The chemical structure of the solvents, as well as their ability to dissolve melamine, have b een determined. The mechanism of melamine dissolution in the reactive solvents has been analyzed by using the H-1-NMR technique. (C) 1998 Jo hn Wiley & Sons, Inc.
