Single component and multi component of iron system colloidal catalyst Fe(naph)2 Al(i- Bu)3 CH2 CHCH2Cl 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

Al(i-Bu)3 existed in associated state and dissociated into ionpair.The reaction between Al(i-Bu)3 and Fe(naph)2 was the main reaction which formed colloidal core.Al(i-Bi)3 reacted on CH2=CHCH2Cl and Al(i-BU)2Cl was yielded which joined the formation of active center on the surface of colloidal core.The excessive Al(i-Bu)3 was dissociated into ionpair which formed double electrode layer

and the double electrode layer kept the colloidal particles relatively stable.The optimal components ratio of the catalyst formed stable colloidal particles which were tiny

uniform and with high catalytic activity.When butadiene was added into the catalytic system the decline of the electroconductivity showed that the active center was the positive ionicity.
