A method for preparing a functionalized polymer, the method comprising the steps of:
- (i) polymerizing monomer with a lanthanide-based catalyst to form a reactive polymer, and
- (ii) reacting the reactive polymer with an azodiester.
A method for preparing a functionalized polymer, the method comprising the steps of:
- (i) polymerizing, with a lanthanide-based catalyst, conjugated diene monomer, and optionally monomer copolymerizable therewith, to form a polymer having a reactive chain end;
- and
- (ii) reacting the reactive chain end of the polymer with an azodiester.
