Single component and multi\|component of iron system colloidal catalyst \Ali\|Bu\-3CH\-2CHCH\-2Cl\ were mixed by different ratios in hydrogenated gasoline medium at 25℃.This paper studied the relationship between the nonaqueous systematic electroconductivity and the concentration of catalyst components.In combination with Tyndall effect,polymerization experimental results,Ali\|Bu\-3 existed in associated state and dissociated into ionpair.The reaction between Ali\|Bu\-3 and Fenaph\-2 was the main reaction which formed colloidal core.Ali\|Bu\-3 reacted on CH\-2CHCH\-2Cl and Ali\|Bu\-2Cl was yielded which joined the formation of active center on the surface of colloidal core.The excessive Ali\|Bu\-3 was dissociated into ionpair which formed double electrode layer,and the double electrode layer kept the colloidal particles relatively stable.
