Abstract

A method of production of modified conjugated diene rubber includes causing an aromatic compound having three or more carbon atoms directly bonded to an aromatic ring in one molecule to react with an alkali metal atom so as to obtain an alkali metal-reacted aromatic compound; polymerizing a monomer at least containing a conjugated diene compound by using the alkali metal-reacted aromatic compound so as to obtain a conjugated diene rubber having an active end; causing the active end of the conjugated diene rubber having an active end to react with an activity control agent so as to obtain a conjugated diene rubber reacted with an activity control agent; and causing the active end of the conjugated diene rubber reacted with an activity control agent to react with a modifier having an alkoxy group and a halogen atom-containing group so as to obtain a modified conjugated diene rubber.
