Abstract

PURPOSE: The anionic polymerization is conducted using an organosodium as a polymerization initiator and an alkylaryl compound as a chain transfer, then the rinsing is effected with an acidic or neutral aqueous alcohol to remove the catalyst residue efficiently, thus producing the titled liquid polymer product.
CONSTITUTION: An organosodium such as benzylsodium is used as a polymerization initiator and an alkylaryl compound such as toluene is used as a chain transfer to effect the anionic polymerization or copolymerization of a conjugate diolefin such as butadiene or of a mixture thereof with an anionically polymerizable vinyl monomer in a polymerization solvent such as hexane. Then, the polymerization mixture is rinsed with an acidic or neutral alcohol solution of 50W95wt% concentration such as methanol to give the objective liquid polymer product.
