| Abstract: | Cyclohexane and nonionic emusifier EA. have been chosen for preparation of PAA with ultra—high molecular weight. Powdery and reapidly dissolved PAA with w≥12×10~6 has been prepared. Factors influencing w and conversion, such as temperature, the concentration of initiator, monomer, emulsifier and the ratio of Vw/Vo have been investigated. |
