摘　　要：综述了以辣根过氧化物酶和漆酶为主要催化剂,催化氧气或过氧化氢等氧化剂和1,3-二酮类化合物反应产生自由基,并由此引发丙烯酰胺、(甲基)丙烯酸酯类和苯乙烯类单体的聚合,在这些文献中,作者们详细讨论了聚合反应条件对反应产物转化率、分子量、分子量分布的影响。通过对反应的深入研究,提出了合理的反应机理。This article reviews literatures on the use of horseradish peroxidase and laccase as main catalysts to catalyze the reaction of oxidants such as oxygen or hydrogen peroxide with 1,3-diketone compounds to produce free radicals,which trigger the polymerization of acrylamide,(methyl)acrylate,and styrene monomers.In these literature,the authors discuss in detail the effects of polymerization reaction conditions on the conversion rate,molecular weight,and molecular weight distribution of the reaction products.Through in-depth research on the reaction,the resonable reaction mechanism was proposed.
