| N-hydroxymethylacrylamide possesses the characteristics of a crosslinking agent monomer due to the presence of two active groups, namely the polymerizable double bond and the hydroxymethyl group, in its molecular structure. The earliest synthesis method was to react acrylamide with formaldehyde to obtain crystalline N-hydroxymethylacrylamide. For instance, foreign scholars have used polyformaldehyde and acrylamide crystals, with trichloroethylene as the solvent, and with metal sodium colloid as the catalyst to produce N-hydroxymethylacrylamide. After the reaction, the system naturally separated into two phases. When the temperature dropped to room temperature, a large amount of N-hydroxymethylacrylamide precipitated out, resulting in the N-hydroxymethylacrylamide product. However, the obtained product needed to be recrystallized using acetone or ethyl acetate. | |||||||||
