锰(Ⅲ)离子可以引发烯类单体自由基聚合。羧酸,α-羟基羧酸对丙烯酰胺聚合有促进作用,其活性顺序为羟基多元羧酸(柠檬酸)>羟基羧酸(乳酸)>羧酸(正丁酸)。测定了在较高酸性([H~+]=3.0M)的硫酸水溶液中,单独Mn~(3+),Nn~(3+)-乙醇酸,Mn~(3+)-乳酸引发丙烯酰胺聚合的活化能与动力学方程。 Manganese (Ⅲ) ions can initiate the radical polymerization of vinyl monomers. Carboxylic acid, α-hydroxycarboxylic acid can promote the polymerization of acrylamide. The order of activity is hydroxy polycarboxylic acid (citric acid)> hydroxycarboxylic acid (lactic acid)> carboxylic acid (n-butyric acid). The results showed that the activation of acrylamide induced by Mn ~ (3 +), Nn ~ (3 +) - glycolic acid and Mn ~ (3 +) - lactic acid in the aqueous solution of sulfuric acid with higher acidity Aggregation of activation energy and kinetic equation.
