摘要
从动力学研究角度出发,指出催化活性中心浓度测定对于烯烃配位聚合反应机理和催化剂研究的重要意义。简要介绍了在烯烃配位聚合领域中应用的各种活性中心浓度测定方法,并对这些方法的特点及存在问题进行了分析和讨论。
The active centre determination plays a vital important role in the investigation of ole-fin polymerization by Ziegler-Natta catalysts. This paper presents a brief review about the various methods employed for determination of the number of catalytic active centres. Typical features of these methods are presented and advantages, as well as shortcomings, of each method are discussed.
