Reactions occurring in melamine-formaldehyde-acrylamide systems in weakly alkaline (pH 8) and weakly acidic (pH 6) media were studied. Possible mechanisms for the incorporation of acrylamide fragments into the melamine-formaldehyde oligomers were considered. It was shown that the addition of acrylamide units to melamine-formaldehyde oligomers proceeds via two stages: the formation of the methylol derivative of melamine and the interaction of acrylamide with methylol groups. This sequence of reactions can be realized only in acidic media.
