| Abstract: | Low-molecular mass acrylamide-acrylic acid copolymer is a kind of new drying strengthening agent for paper manufacturing industry. The copolymeric reaction process is studied by uniform design. The optimal technological conditions of synthesizing low-molecular mass acrylamide-acrylic acid copolymer are obtained: the temperature of initiation is 25℃, the concentration of acrylamide is 3.2 mol/L, the concentration of acrylic acid is 0.75 mol/L, the concentration of potassium persulfate is 0.0009mol/L, the concentration of sodium bisulfite is 0.0023 mol/L, the concentration of cupric bromide is 0~0.0004 mol/L. |
