氧化还原

In this article, the factors that affect molecular weight and solubility of polyacrylamide are studied and suitable initiator system is selected. The optimum parameters of copolymerizing process are obtained as follows: the molar proportion of acrylamide and sodium acrylate is 7:3, the monomer concentration is 30%, pH value of solution is 12, the oxidizer (K2S2O8) concentration is 0.1%, the reducing agent (NH2CONH2) concentration is 1%, the chain-transfer agent concentration is 0.4%. The initial reaction temperature is 35℃.
