| Abstract: | high molecular cationic polyacrylamide with molecular weight more than 2.0 million was prepared by poly- merization of propenamide. Effect of polymerization technological conditions on polymer molecular were discussed. Optimum technology of polymerization was obtained. Optimum technological conditions ： mass fraction of initiating agent is 5 ×10^5 %, mass fraction of monomer is 25 %, trigger temperature is at 10 - 15 ℃, range of pH that polymerization system appropriate is at7 -8. |
