Using electric conductivity and UV-Vis spectroscopy, the interaction between the catalyst components was further analyzed. The conclusions as follows were further verified: the catalyst components reacted with each other in the form of ionic pair. There existed Ni(0)-atom cluster (Ni^0)~m in aged solution of (Ni)-(Al). The cluster was very stable because of absorption of Ninaph and became bigger to form colloidal particles while adding (B). The active centers were located on the surface of colloidal particles. Butadiene didn't take part in the formation of active centers.
