Abstract
Provided are vinyl-cis-polybutadiene in which content of an insoluble matter portion in boiling n-hexane (HI) is 9 to 23% by weight, long chain branch index (LCB index) is 1.50 to 5.95, and a ratio (Tcp/ML1+ 4 l between viscosity in 5% by weight of toluene solution (Tcp) and Mooney viscosity at 100?C (ML 1 +4 ) of a soluble matter portion in boiling n-hexane is 2.07 or less, and a method of producing the same including a cis polymerization step (a) and a vinyl polymerization step (b), in which an addition amount of the 1,4 polymerization catalyst relative to 1 mol of the conjugated diene monomer is 1.2 to 2.7 ?mol, an addition amount of the 1,2 polymerization catalyst relative to 1 mol of the conjugated diene monomer is 2.5 to 18.0 ?mol, and an addition amount of the 1,2 polymerization catalyst relative to 1 mol of the entire organic aluminum compounds comprising the first and the second organic aluminum compounds is 0.0015 to 0.0150 mol.
