1. A method of preparing styrene polymer, the method comprising:
homogeneously mixing a styrene monomer; a cocatalyst mixture of Group 13 metal-containing organic metal compound cocatalyst and an inert organic solvent; and a catalyst mixture of a metallocene catalyst and the inert organic solvent using a high speed homogenizing mixer to obtain a mixed and homogenized mixture; and
providing the homogenized mixture to a reactor to initiate polymerization.
