The Effects of Initiating Systems on CPAM Relative Molecular Weight and Strength Properties of Paperboard

initiator is one of the most important conditions of synthesizing efficient strength agent CPAM. To begin with initiating mechanism, three redox systems of acrylamide aqueous polymerization (NH4)2S2O8/ Na2 SO3, K2S2O8/NaHSO3 and K2S2O8/Na2 S2O4 have been studied. The effects of different kinds of initiator, initiator concentration, and monomer concentration as well as polymerization temperature on relative molecular weight and strength effects of CPAM have been investigated. K2S2O8/Na2 SO3 is the most useful system in synthesizing efficient strength agents.
