| Abstract: | Ultra high molecular weight polyacrylamide （HPAM） was synthesized via aqueous dispersion poly merization by introducing the compound redox system to initiate AM solution homogeneous polymerization. The time - kinetic curves of the aqueous dispersion polymerization was comprehensively analyzed. The results show that the relatively high molecular weight polyaerylamide can be synthesized, when the concentration of AM is 31 %, the concentration of bifunctional initiator is 10mg/L, the polymerization temperature is 6℃, the dosage of azo com pounds is 25mg/L. |
