PURPOSE:To obtain a chemically stable and practical packing agent which is relatively easy to manufacture with a broad range of analyzable compound, by using an optically active monomer given by a specified formula. CONSTITUTION:A polymer comprising an optically active monomer given by the formula I and a monomer by the formula II is immobilized to a silica gel to form a packing agent for optical resolution. In the formula I, R1 represents a phenyl group, a benzyl group, 1-naphthyl group, 2-naphthyl group, 1-naphthyl methyl group, 2-naphthyl methyl group, 3-indolyl methyl group or a cycohexyl methyl group or a phenyl group, benzyl group, 1-naphthyl group, 2-naphthyl group, 1-naphthyl methyl group, 2-naphthyl methyl group or 3-indolyl methyl group which is replaced with a lower alkyl group, carboalkoxyl group, halogen atom or hydroxyl group, R2 a lower alkyl group, R3 hydrogen atom or methyl group or * asymmetric carbon atom. In the formula II, R4, R5 and R6 each represent an alkyl group, alkoxyl group, hydroxyl group or halogen atom. provided that at least one is an alkoxyl group or halogen atom. |
