Research and Production of Low-molccular Weight Acrylic Amide-Acrylic Acid Copolymer

Reaction technology of acrylic amide and acrylic acid copolymer initiated by potassium supersulphate sodium bisulfite initiator was introduced. The optimum technology condition for synthesising low molccular weight acrylic amidc acrylic acid copolymer series products was given, for example the temperature of initiation is 25℃, the concentration of acrylic amide is 3.5 mol/L, the concentration of acrylic acid is 0.7 mol/L, the concentration of potassium persulfate is 0.001 1 mol/L, the concentration of of sodium bisulfite is 0.002 9 mol/L, the concentration of cupric bromide is 0～0.000 45 mol/L.
