Procedure

Preparation of polystyryllithium by anionic polymerization of styrene, preparation of a polymerization initiator compound by addition reaction of butadiene, and polymerization of methyl methacrylate in the presence of an organoaluminum compound were successively performed in the same way as in Example 3 except that a solution prepared by mixing 1.0 ml of a toluene solution containing 0.80 mmol of isobutylbis(2,6-di-tert-butyl-4-methylphenoxy)aluminum with 0.22 g of 1,2-dimethoxyethane was used instead of 1.0 ml of the toluene solution containing 0.80 mmol of diisobutyl(2,6-di-tert-butyl-4-methylphenoxy)aluminum.
