<p><P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a modified cis-1,4-polydiene having both high cis-1,4-bond quantity and high functionality. <P>SOLUTION: This modified cis-1,4-polydiene is manufactured by a method comprising a process (1) in which a reactive polymer is prepared by polymerizing a conjugated monomer in the presence of an organic solvent which is less than about 20 wt.% of the total of the monomer, the organic solvent, and the polymer produced by the result of the polymerization, using a lanthanide catalyst which is a combination or a reaction product of (a) a lanthanide compound, (b) an aluminoxane, (c) an organic aluminum compound other than an aluminoxane, and (d) a compound containing a halogen, and a process (2) in which the reactive polymer is brought into contact with a modifier. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
