Abstract
An alkali metal-reacted aromatic compound which has three or more carbon atoms which are directly bonded to alkali metal atoms and aromatic rings in one molecule is used as a polymerization initiator to polymerize a monomer mixture which is contains at least one conjugated diene compound to thereby produce a radial conjugated diene polymer. Further, active ends of the polymer having active ends which is obtained by this method is made to react with a modifier which can react with the active ends to thereby produce an end-modified radial conjugated diene polymer. According to the present invention, it is possible to provide a method of production of the radial conjugated diene polymer which gives a high degree of freedom of polymer design and easy control of the polymer structure.
