Use | N-(3-dimethylaminopropyl) methacrylamide (DMAPMA) is a fluid at room temperature and is a widely used functional monomer. It belongs to the unsaturated tertiary amine, because there are tertiary amine groups and polymerizable vinyl groups in the molecular structure, the chemical properties are active, and the homopolymerization, copolymerization and quaternization reaction can be further occurred. It is characterized by high monomer activity, the formation of polymer product molecular weight and cation characteristics, water solubility and alcohol solubility are good, the product is widely used in water treatment industry as a flocculant, adsorbent, reduce BOD, COD water treatment agent and the daily chemical industry, paper industry can be used for new distillation filter aid and reinforcing agent, cationic agent and crosslinking agent in sizing agent, pharmaceutical industry, fiber industry, oil and gas development, photosensitive material |
