Progress in Research of Late-Transition Metal Catalysts for Polymerization of Methyl Methacrylate

介绍了近年来用于甲基丙烯酸甲酯聚合的后过渡金属催化剂的研究进展情况,着重阐述了镍系、铜系、铁系及钴系金属配合物催化剂的研究进展,并对各类催化剂的催化活性、所制备的聚甲基丙烯酸甲酯的相对分子质量及其分布、聚合物的微观结构等进行了比较。指出在催化剂结构中引入吸电子基团可提高其催化活性,进一步研究催化剂结构如何有效控制聚合物微观结构等构-效关系是其重要发展趋势之一。

The progress in the research of late-transition metal catalysts for the polymerization of methyl methacrylate was reviewed,mainly including the metal complex catalysts of nickel system,copper system,iron system and cobalt system.Their catalytic activity of various kinds of catalysts,the relative molecular mass and microstructure of the prepared poly-methyl methacrylates and the distribution of the relative molecular mass are compared.It was proposed that the introduction of electron-withdrawing group to the structure of catalysts is necessary to improving their catalytic activity,and the further research of the structure of catalysts to effectively control the microstructure of Poly(methyl methacrylate)is one of the future research directions for the polymerization of methyl methacrylate.
