OPTICALLY ACTIVE COPOLYMER, PROCESS FOR PRODUCING THE SAME, AND PACKING FOR CHROMATOGRAPHY COMPRISING THE COPOLYMER

摘要

An optically active copolymer characterized by being obtained by copolymerizing a bulky methacrylic ester which, when caused to homopolymerize, gives a helical polymer with a 1,1-aromatic-substituted ethylene monomer having a polymerizable exomethylene group, and by being represented by the following structural formula (1); and a packing for chromatography for optical-isomer separation which comprises the copolymer. Structural formula 1: In the formula, Ar is an aromatic ring; R<SUP>1</SUP> and R<SUP>2</SUP> each is hydrogen, an organic group, or a heteroatom; R<SUP>3</SUP> and R<SUP>4</SUP> each is hydrogen, a heteroatom, or an organic group; R<SUP>11</SUP> is triarylmethyl optionally having a crosslinked structure; m and n each is an integer of 2 or larger; -X- is -(CH<SUB>2</SUB>)<SUB>q</SUB>-, an aromatic group, vinyl, a heteroatom, or a group having a heteroatom; and q is an integer of 0 or larger. The copolymer has sufficient solvolysis resistance, is useful as a stationary phase for chromatography, polarization-absorbing/luminescent material, charge-transporting material, etc., and has excellent chirality-identifying ability.
