本文详细地研究了一类新型稀土定向聚合催化剂Nd(OR)_(3-n)Cl_n-AlEt_3的结构和聚丁二烯微观结构的关系,发现微观结构与催化剂中M_T-X键上电子对的偏移程度有关,如果用诱导效应指数来表示这种电子对偏移,则微观结构和诱导效应指数间存在线性关系。对文献数据的处理结果支持这一结论。
In this paper, we studied in detail the relationship between the structure of a new type of rare-earth oriented polymerization catalyst Nd (OR) _ (3-n) Cl_n-AlEt_3 and the microstructure of polybutadiene and found that the M_T- Of the degree of offset, if the induction effect index expresses this electron-pair offset, there is a linear relationship between the microstructure and the induction effect index. The data processing results support this conclusion.
