Process for preparation of high 1,4-CIS polybutadiene
This invention relates to a process for preparation of high 1,4-cis polybutadiene and more particularly, to the process for preparing polybutadiene by polymerizing 1,3-butadiene monomer in the presence of a catalyst prepared by aging a mixture of a neodymium salt compound, a nickel salt compound, an organoaluminium compound and a borontrifluoride complex compound in the presence or absence of a conjugated diene compound. With much remarked catalytic activity, polybutadiene with a very high 1,4-cis content can be prepared in a high yield using a small amount of catalyst.
