HCID 159984Methyl 2-methylprop-2-enoate;styrene

Procedure

Preparation of polystyryllithium by anionic polymerization of styrene, preparation of a polymerization initiator compound by addition reaction of a conjugated diene compound, 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 instead of butadiene, isoprene of the mole equivalent thereto was used as the conjugated diene compound.
