摘要

聚合物的立体结构可显著的影响其性质和功能

Lewis 酸基于其独特的反应性和选择性且反应条件温和而广泛应用于有规立构自由基聚合反应

特别是利用稀土金属（如Y、Sc、Yb、La、Pr、Lu、Tm 等）的三氟甲基磺酸盐作为自由基聚合的催化剂

可有效提高丙烯酸酯类、（甲基）丙烯酰胺类聚合物的立构规整度。本文介绍了Lewis 酸在自由基聚合中的应用概况

重点综述了稀土金属的三氟甲基磺酸盐在丙烯酸酯类单体和（甲基）丙烯酰胺类单体的有规立构自由基聚合中的研究进展。

Abstract

The property and function of a polymer was significantly influenced by their stereoregularity. Lewis acids were widely applied in stereocontrol radical polymerization because of their unique reactivities and selectivities

as well as mild reaction conditions.Among the many Lewis acids

rare earth metal

such as Y

trifluoromethanesulfonates were particularly effective in increasing the isotacticity of various polymethacrylates and poly (meth) acrylamides.In this paper

the application of Lewis acids as catalyst in radical polymerization was introduced

and the progress in stereospecific radical polymerization of methacrylates and (meth) acrylamides catalyzed by rare earth metal trifluoromethanesulfonates was emphatically reviewed.
