The factors which affect the average molecular weight of the polymer of AM and DMDAAC were investigated. The optimal reaction conditions are as follows: the concentration of monomer AM was 30%, while DMDAAC was 5%; the reaction temperature was 30℃, the amount of initiators at the low temperature stage was 0.05‰(compared to the weight of the monomers joining the polymerization), while V-50 was 0.025‰, the weight ratio of potassium persulphate to sodium bisulphite is 1:1, the amount of carbamide was 40‰, and complexing agent was 0.05‰, besides, aerate nitrogen gas for 8min, then the high molecular weight polymer (M=1.217×10^7) could be got after 16h reaction.
