Polymerization of conjugated dienes |
| abstract |
The invention relates to a method of polymerizing one or more conjugated diene monomers to a polymer having an exceptionally high cis content employing a three component catalyst comprising (a) a rare earth compound, (b) an organo magnesium compound and (c) a Lewis acid in which a particular order of component addition is used. Under optimum conditions it is possible to obtain nearly 100% conversion to polymers of 98% or more cis content at very low concentrations of rare earth compound with respect to monomer. |
