-14- -14- A METHOD FOR PRODUCING FUNCTIONALIZED CIS-14-POLYDIENES HAVING HIGH CIS-14-LINKAGE CONTENT AND HIGH FUNCTIONALITY

摘要

the present invention is a high cis-1,4-bond content having a functionalized cis and high polarity functional combination-l, 4-polydienes containing the production method, the resulting polymer and the polymer which relates to a vulcanization product. The functionalization of the present invention cis-1,4-polydiene is (1) a monomer, in the presence of an organic solvent of an organic solvent and based on the total weight of the resulting polymer is less than about 20% by weight, (a) the lanthanide compound , (b) an aluminoxane, (c) an organoaluminum compound other than an aluminoxane, and (d) preparing a reactive polymer by a lanthanide-based catalyst in the reaction product thereof or a combination of a halogen-containing compound polymerizing a conjugated diene monomer; And (2) is produced by a method comprising the step of contacting the functional agent to the reactive polymer.
