  摘要：

  本发明揭示了一种线性嵌段共聚物，包括至少一个三嵌段I-B-I，其中I是至少5个碳原子的聚合共轭二烯块，例如异戊二烯，B是至少4个碳原子的聚合共轭二烯块，不同于式（1）的共轭二烯块，例如1,3-丁二烯。B块被选择性氢化，而每个I块保留足够的原始不饱和度以使共聚物硫化。还揭示了一种替代的线性嵌段共聚物，其中至少包含一个由芳基取代的烯烃制成的第一聚合物块的三嵌段，例如苯乙烯，以及用于聚合块I的共轭二烯，用于聚合块B的第二个中间聚合物块和与第一聚合物块相同的第三聚合物块。在这种替代共聚物中，中间块也被选择性氢化，从而使末端聚合物块具有足够的双键以使共聚物硫化。可以通过含有乙烯不饱和度的末端块交联或功能化聚合物。还揭示了由与线性嵌段共聚物相同的单体制成的随机和星形嵌段共聚物和随机共聚物。还揭示了生产和选择性氢化聚合物的方法。

  The subject invention relates to a technique for synthesizing rubbery non-tapered, random, copolymers of 1,3-butadiene and isoprene. These rubbery copolymers exhibit an excellent combination of properties for utilization in tire sidewall rubber compounds for truck tires. By utilizing these isoprene-butadiene rubbers in tire sidewalls, tires having improved cut growth resistance can be built without sacrificing rolling resistance. Such rubbers can also be employed in tire tread compounds to improve tread wear characteristics and decrease rolling resistance without sacrificing traction characteristics. This invention more specifically discloses a process for the synthesis of isoprene-butadiene rubbers which comprises copolymerizing isoprene monomer and 1,3-butadiene monomer in an organic solvent in the presence of a catalyst system which is made by the sequential steps of (1) mixing (a) an organoaluminum hydride, (b) a member selected from the group consisting of aliphatic alcohols, cycloaliphatic alcohols, aliphatic thiols, cycloaliphatic thiols, trialkyl silanols, and triaryl silanols, and (c) optionally, 1,3-butadiene in an organic solvent to produce a modified organoaluminum catalyst component; (2) adding an organometallic compound which contains a metal from Group III-B of the Periodic System to the modified organoaluminum catalyst component to produce a Group III-B metal containing catalyst component; and (3) adding a compound which contains at least one labile halogen atom to the Group III-B metal containing catalyst component.
