| Abstract: | The catalytic effect of MoCln(OE)4-n-(i-Bu)2AlOPh on polymerization of butadiene in hydrogenated gasoline is studied (B is alkyl, cycloheptyl, phenyl of C4-16). In the system, the solubility and the catalytic activity of the catalyst are not related to the number of carbon atom in R group whether odd or even. The B group with primary and secondary carbon atom have a rather great influence on the catalytic activity. When B is an alkly, the catalytic activity incerases and the range of Al/MO values that keep higher conversion of butadiene is broadened with increasing the size of R group. The content of 1,2-units in the polymers did not change with the size of R group. |
