Abstract

The selection of the catalyst is central to being able to control features and to better understand microstructures of polymers. New single-site metal alkoxide catalysts allow chemists to prepare regio/stereo regular polymers or copolymers that meet increasingly demanding performance requirements. These catalysts produce high molecular weights polymers with narrow polydispersity indexes or living properties and essentially regular polymers in structures. This review includes the synthesis, activity, and mechanistic aspects of especially single-site metal alkoxide catalysts with examples from my previous studies and recently published similar articles, beginning with an extensive survey on the aluminum, titanium, zirconium, and tin catalysts used to make polyethers, polyesters, and their derivatives. This review also compares the effects of ligands, substituents on ligands, and central metal atoms on ROP reactions. This review will provide the basis for the researchers who seek the new synthesis and application of catalysts in the future.

单中心金属醇盐配合物作为环状化合物开环聚合催化剂的最新研究

摘要

催化剂的选择对于能够控制特征和更好地理解聚合物的微观结构至关重要。新型的单中心金属醇盐催化剂使化学家可以制备能够满足日益增长的性能要求的区域/立体常规聚合物或共聚物。这些催化剂产生具有窄的多分散指数或活性的高分子量聚合物，并且在结构上基本上是规则的聚合物。这篇综述包括特别是单中心金属醇盐催化剂的合成，活性和机理方面的研究，以及我以前研究和最近发表的类似文章中的实例，首先是对用于制造铝，钛，锆和锡催化剂的广泛研究聚醚，聚酯及其衍生物。这篇评论还比较了配体的作用，配体上的取代基和ROP反应上的中心金属原子。这篇综述将为将来寻求催化剂的新合成和应用的研究人员提供基础。
