| titleOfInvention | Process for producing polybutadiene rubber with enhanced mechanical strength |
| abstract | A polybutadiene rubber having an enhanced mechanical strength is produced in such a manner that the contents of water and carbon disulfide in a solution of 1,3-butadiene and carbon disulfide in an inert organic solvent is controlled to 0.2 to 5 m moles and 20 m moles or less, respectively, per liter of the 1,3-butadiene-carbon disulfide solution; a first polymerization mixture is prepared from the controlled 1,3-butadiene-carbon disulfide solution, an organic aluminum compound of the formula Al R n X 3-n , wherein R = C 1-6 alkyl, phenyl or cycloalkyl, X = halogen, and n = 1.5-2.0, and a cobalt compound, for example, by aging a mixture of the controlled 1,3-butadiene-carbon disulfide solution with the aluminum compound for at least one minutes and then by admixing the aged mixture with the cobalt compound; the first polymerization mixture is subjected to a cis-1,4- polymerization; a second polymerization comprising the resultant cis-1,4-polybutadiene, non-reacted 1,3-butadiene, the inert organic solvent, an organic aluminum compound of the formula AIR3, a cobalt compound, and the carbon disulfide is subjected to a 1,2-polymerization to produce a polybutadiene rubber consisting essentially of ε% to 30% by weight of a boiling n-hexane-insoluble fraction and 70% to 95% by weight of a boiling n-hexane-soluble fraction thereof; and after the 1,2-polymerization is shortstopped, the resultant polybutadiene rubber is isolated from the 1,2- polymerization mixture. |
