%X Fractionation of isotactic polystyrene based on phase equilibrium was preformed by using o-dimethylphthalate (DMP) as a solvent and cyclohexanol (CHA) as a nonsolvent. Fractionation with semi-preparative GPC was also preformed. The effect of fractionation based on phase equilibrium is limited, but the result obtained from semi-preparative GPC is quite well.
