Abstract
A kind of redox initiator containing functional monomer was used to synthesize polyacrylamide through inverse microemulsion,and the result of the orthogonal experiments showed that mfunctional monomer/mreductant(the mass ratio) and the reaction temperature were the major factors which affected the molecular-weight of polyacrylamide.The optimal reaction conditions were as follows:monomer mass concentration was 30%,the reaction temperature was 30℃,the initiator mass concentration was 0.15%,mfunctional monomer/mreductant was 0.25.The molecular-weight of polyacrylamide with 1.09 × 107 was synthesized under this optimal conditions.FT-TR spectrum had been used to characterize the synthesised PAM.
