Procedure

In a similar manner for polymerization to that in Example 1, a monomer of 60 g of n-dodecyl methacrylate, 24 g of ethylene glycol dimethacrylate, and 30 g of ethyl acetate was polymerized in an aqueous suspension system to obtain a substrate consisting of hard spherical polymer particles. Of the thus obtained particles, those of 53 to 250 micrometers in diameter were filled into a column of 10 mm in diameter at a packed height of 193 mm, and separation of a 1:1 by weight mixture of nitrobenzene and 2-methylnaphthalene dissolved in an eluent consisting of a 60:25:15 by volume mixture of methanol, tetrahydrofuran and water in an amount of 0.3 ml was carried out at a velocity of the eluent of 1.7 ml/min. The thus obtained elution curve is shown in FIG. 4.
