| Abstract: | With a new series of binary catalyst Nd(OR)3-nCln-AlEt3 prepared in our laboratory, the effect to catalyst composition on the microstructure of polybutadiene was studied in detail. A linear relationship is found between the variation of the microstructure of the polymer obtained and the iductive effect index (I) which reprepresents the magnitude of the displacement of paired valence electrons on transition metal-halogen bond (MT-X) of the catalyst. This linear relationship also holds in dealing with the data published in the literature. |
