| abstract | ABSTRACT OF THE DISCLOSURE A polybutadiene having an average 1,2-bond content of 18 to 32% by mole, a branched polymer chain content of 60% by weight or more and a Mooney viscosity at 100°C of 40 to 90, the viscosity of a 5% by weight concentration solution of this polybutadiene in styrene at 25°C being 60 to 90 cps, and a process for preparing the polybutadiene comprising starting the polymerization of 1,3-butadiene in an inert hydrocarbon solvent in the presence of a Lewis basic compound and an organolithium compound, the latter compound being in an amount of 0.5 to 3 millimoles per 100 g of 1,3-butadiene, at a temperature selected from the range of 30 to 80°C, carrying out the polymerization by controlling the temperature so that the temperature at the end of polymerization may be 5 to 40°C higher than the temperature at the start of polymerization, and adding to the resulting polymer solution a poly-functional halogen compound in an amount of 0.6 to 1 equivalent per equivalent of the organolithium compound to further react the polymer with the polyfunctional halogen compound. |
