The water-soluble monomer dimethylaminoethyl methacrylate (DM), with low-temperature plasma initiated its aqueous solution polymerization. The effects of various factors on the yield of polymer were investigated. The experimental results showed that the mass fraction of monomer was 48.5 3%, and the plasma discharge power was 10 W. In the experimental range, with the discharge time (0-6 5 s) and after the polymerization time (3 ~ 2 4d), the polymer yield increased. Polymerization reaction has greater selectivity to the solvent, of which the best effect of aqueous solvents. In addition, the polymer has a greater water absorption capacity (100 g / g).
