一、引言在高分子合成的领域内,如何获得规整结构的聚合物是早为人们注意的问题。目前不仅可用离子型催化剂,而且也用自由基引发剂来制备规整的结晶高聚物。但其中以Ziegle-Natta型催化剂显得更为突出,这方面已进行了大量的研究工作,新的催化系统(均相和异相)在不断出现;不过其聚合机理尚在争论中,仍为今后科学研究的主要对象(目前大多数作者认为是配位阴离子聚合)。动力学研究不仅对聚合机理的探索,而且也为工业生产提供有益数据。用ziegler-Natta型催化剂聚合α-烯类的动力学与 I. INTRODUCTION In the field of polymer synthesis, how to get a regular structure of polymer is an issue that people pay attention as early as possible. At present, not only ionic catalysts but also free radical initiators are used to prepare structured crystalline polymers. However, Ziegle-Natta type catalysts are more prominent, and a great deal of research work has been carried out in this area. New catalytic systems (homogeneous and heterogeneous) are constantly emerging; however, their polymerization mechanism is still under debate and will remain for the future The main object of scientific research (currently most authors consider coordination anionic polymerization). Kinetic studies not only explore the polymerization mechanism, but also provide useful data for industrial production. Kinetics of Polymerization of α-Olefins with Ziegler-Natta Catalysts
