Aim\ To study the effect of initiating systems in synthesis of relative molecular weight of polyacrylamide. Methods\ To begin with initiating mechanism

five Redox initiators of acrylamide aqueous polymerization has been studied. The effects of different kinds of initiator

initiator concentration

monomer concentration as well as polymerization temperature on relative molecular weight of polyacrylamide have been investigated. Results\ Every initiating system remarkably affects the relative molecular weight of the synthesized polyacrylamide. Conclusion\ K 2S 2O 8 Na 2S 2O 4 system is an effective initiating system for the synthesis of high relative molecular weight polyacrylamide.
