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 2 except that the temperature when diisobutyl(2,6-di-tert-butyl-4-methylphenoxy)aluminum was added, the temperature when methyl methacrylate was added, and polymerization temperature were changed from −30° C. to 0° C. and the time for polymerization of methyl methacrylate was changed from 2 hours to 1 hour.
