N-Methylol Acrylamide
CAS: 924-42-5 Chemical Formula：C4H7NO2
Properties
White crystals, soluble in water and hydrophilic solvents, soluble in fatty acid lipids, almost insoluble in hydrocarbons, halogenated hydrocarbons and other hydrophobic solvents. This product is a self-inbred active monomer, containing a double health conjugated with hydroxyl group, which is prone to condensation reaction in neutral or alkaline media. It is unstable in moist air or water, easy to polymerize, and will quickly polymerize into insoluble resin when heated in the presence of acid in aqueous solution. If copolymerized with acrylate monomers, hydroxymethyl is introduced and can be crosslinked by heating alone.
