Abstract
A method for polymerizing isoprene, the method comprising (i) providing a dilithium initiator; (ii) introducing the dilithium initiator to isoprene monomer to form a polymerization mixture; and (iii) allowing the isoprene monomer to polymerize and form polyisoprene, where the polyisoprene is characterized by a monomodal molecular weight distribution.
