<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a butadiene-based polymer in which the content of the cis-1,4 bond of a butadiene monomer unit is high. <P>SOLUTION: The method of manufacturing a butadiene-based polymer is characterized by polymerizing the monomer which at least contains 1,3-butadiene under the presence of: a catalyst system; and a 2-10C unsaturated hydrocarbon which has a triple bond. The catalyst system comprises: a rare earth element-containing compound (A component) of atomic numbers 57-71 of the periodic table or a reaction compound of the compound with a Lewis base; an organoaluminum compound (B component) shown by general formula: AlR<SP POS="POST">1</SP>R<SP POS="POST">2</SP>R<SP POS="POST">3</SP>, wherein R<SP POS="POST">1</SP>and R<SP POS="POST">2</SP>identically or differently are a 1-10C hydrocarbon group or a hydrogen atom, R<SP POS="POST">3</SP>is a 1-10 hydrocarbon group, provided that R<SP POS="POST">3</SP>may be the same as or different from the R1 or R2; and at one kind of halogen compound (C component) among a Lewis acid, a complex compound of a metal halide and a Lewis base, and an organic compound containing an active halogen. <P>COPYRIGHT: (C)2012,JPO&INPIT |
