A STUDY OF POLYBUTADIENE SYNTHESIS WITH MoCln(OR)4-n-(i-Bu)2AlOPh AS A CATALYST

Received Date: 17 February 1985

The catalytic effect of Mo Cln (OR)4-n-(i-Bu)2AlOPh on the polymerization of butadiene inhydrogenated gasoline is studied (R is alkyl, cycloheptyl, phenyl of C4-16). In this system, the solu-bility and the catalytic activity of the catalyst do not depend on whether the number of carbon atomsin R group is odd or even. The R group with the primary and secondary carbon atom has a fairlygreat influence on the catalytic activity. When R is an alkyl, the catalytic activity increases and therange of Al/Mo values that keeps higher conversion of butadiene is broadened as the size of the R group increases.The content of 1,2-units in the polymer hardly varies with the size of the R group.
