    • Disclosed is a novel high 1,4-cis polybutadiene-polyurethane copolymer and a preparation method thereof. The present invention provides a high 1,4-cis polybutadiene-polyurethane copolymer represented by the following formula 1 and having an average molecular weight of at least 100,000, and a method for preparing the high 1,4-cis polybutadiene-polyurethane copolymer that includes polymerizing 1,3-butadiene or butadiene derivatives with a catalyst comprising a rare earth compound, a halogen-containing compound and an organoaluminum compound in the presence of a non-polar solvent, to prepare a polybutadiene having a high 1,4-cis content of at least 95%; and then introducing a polyurethane group to the polybutadiene. The high 1,4-cis polybutadiene-polyurethane copolymer thus obtained exhibits low cold flow and high affinity to silica or carbon black in admixture as well as excellent in elasticity and abrasion resistance: where l, m, n and o represent the number of repeating unit, 1 is 94 to 99%, m is 0 to 5%, n is 0 to 5%, l+m+n=100%, l/(m+n) is 15 to 100, o is 1 to 100%; and A and Y are C1-C20 alkyl or aryl, respectively.

    • The present invention relates to a method for preparing a high 1,4-cis polybutadiene having a controlled cold flow and, more particularly, to a novel method for preparing a high 1,4-cis polybutadiene having a controlled cold flow that involves initiating polymerization of a 1,3-butadiene in the presence of a non-polar solvent using, as a polymerization catalyst, a complex prepared by mixing a neodymium compound with or without a conjugated diene compound, a halogenated organoaluminum compound or a halogenated organic compound, and an organoaluminum compound irrespective of the addition order of the catalyst; and adding an organoborane compound as a cold flow controller of 1,4-cis polybutadiene after a predetermined time of the polymerization. Accordingly, a high 1,4-cis polybutadiene having an efficiently controlled cold flow can be prepared without causing a significant increase in the Mooney viscosity (molecular weight), an odor (bad smell), and a reduction in 1,4-cis content and polymerization yield.
    • 本发明涉及一种制备具有受控冷流的高1,4-顺式聚丁二烯的方法,更具体地说,涉及一种制备具有控制冷流的高1,4-顺式聚丁二烯的新方法,其涉及引发聚合 使用作为聚合催化剂的非极性溶剂存在下的1,3-丁二烯,通过将钕化合物与或不与共轭二烯化合物,卤化有机铝化合物或卤化有机化合物混合制备的络合物和 有机铝化合物,而不考虑催化剂的加成顺序; 并在预定的聚合时间之后加入有机硼烷化合物作为1,4-顺式聚丁二烯的冷流控制器。 因此,可以制备具有有效控制的冷流的高的1,4-顺式聚丁二烯,而不会导致门尼粘度(分子量),气味(难闻气味)的显着增加和1,4-顺式含量的降低 和聚合产率。
