Abstract:
A method of preparing a silane-functionalized polymer, the method comprising: preparing a polymerization system including a cis-1,4-polydiene by introducing a lanthanide-based catalyst and a conjugated diene monomer; and adding a hydrosilane compound to the polymerization system including a cis-1,4-polydiene.
