| Abstract: | Dominated by redox initiation system,a new compound initiating system is formed in conjunction with other initiation. In condition of low temperature,aqueous solution copolymerization is produced to obtain acrylamide and acrylic acid copolymer with high molecular weight. Examining the impact of factors to polymerization,and the most optimum process conditions is ultimately determined: Monomer concentration is 0.0035mol/g,redox initiator is 14mg/L,EDTA is 10mg/L,AZO is 35mg/L,temperature of system is 0℃,pH value is 7.0. The polymer molecular weight is 1.943×107. |
