1. A method for preparing a coupled polymer, the method comprising the steps of:
(i) polymerizing monomers to form a reactive polymer, where the monomer includes conjugated diene monomer, where said step of polymerizing employs a coordination catalyst, and where said reactive polymer has a reactive chain end, and (ii) reacting the reactive polymer with a glycidic ester. |
