Investigations on the properties of acrylamide-modified melamine resins.

Part III. Explanation of the mechanism of action of acrylamide

as modifier of melamine—acetone—formaldehyde resins

Summary

Dissolution of acrylamide in the reactive solvent—melamine system was studied in terms of 1H NMR spectra (Figs. 2–5). Acrylamide did not polymerize during the dissolution. It reacted but slightly with the formaldehyde released in the reactive solvent (a product of reaction of acetone with CH2O used in large excess) to yield hydroxymethyl acrylamide derivatives. These derivatives condense with hydroxymethyl derivatives of melamine and reactive solvent incorporated in the system. The extent of this reaction is low; therefore, acrylamide should be treated primarily as a physical modifier.
