摘要： A process for producing a polybutadiene is provided wherein, first, 1,3-butadiene is polymerized in the presence of a particular cis-1,4-polymerization catalyst and subsequently, the polymerization is continued in the presence of a particular 1,2-polymerization catalyst. The resulting polybutadiene is characterized as containing 2 to 40% of the 1,2-structure, the melting point of the 1,2-structure portion being 110.degree. to 215.degree.C, and containing 60 to 98% of the cis-1,4-structure and having an intrinsic viscosity [.eta.] of 0.9 to 8 in tetraline at 135.degree.C. A vulcanized product of the polybutadiene is characterized as possessing improved tear strength, flex-crack resistance and tensile strength.

摘要： Novel alternating copolymers of conjugated dienes and conjugated polar vinyl monomers, wherein the conjugated diene unit is connected in a trans-1,4 form and the conjugated polar vinyl monomer unit and the conjugated diene unit are bonded alternately, are produced efficiently by copolyermizing these monomers in a non-aqueous medium at rather low temperature by using a catalyst system prepared by admixing a selected transition metal compound and an organoaluminum halide in the presence of the polar vinyl monomer or another selected Lewis base. The alternating copolymer here obtained has a regular structure, on this account, for example, the butadiene/acrylonitrile elastic alternating copolymer can be oriented and crystallized under a highly stretched condition.
