A method comprising: (a) forming a living liquid polymer, wherein said living liquid polymer is anionically initiated and comprises a cation; (b) adding a functional initiator precursor of the formula FI-H, wherein H is hydrogen and FI is a functional group, said H terminates said living liquid polymer resulting in said liquid polymer having a number average molecular weight of about 20,000 (g/mole) to about 100,000 (g/mole), and said FI and said cation form a functional initiator; (c) adding monomer, wherein said functional initiator initiates anionic polymerization of said monomer; and (d) terminating the polymerization reaction initiated in step (c). Steps (a) through (c) may be conducted in a single reactor, allowing a liquid polymer to be dispersed in a functionalized polymer in a single polymerization step. Thus, the liquid polymer does not have to be handled separately and processing efficiency is improved. |
