Inverse Suspension Polymerization of Acrylamide

Li Xiaofu and Li Miangui(Hubei Chemistry Research Institute,Wukan 430074)  
Rapidly dissolving powdery polyacrylamide with molecular weight higher than l0 ̄7 hasbeen prepared by inverse suspension polymerization (ISP).Factors which influence themolecular weight,such as temperature,monomer concentration,initiator concentration,emulsifier concentration,water to oil ratio,and the molar ratio of additives,have beenstudied.Phase inversion during the polymerization process has been confirmed by conductivitymeasurement.It is discovered that sodium formate is a good transfer agent for the system.
