摘要:
A polymerizable polymer is obtained by the anionic polymerization and termination by use of a vinyl monomer. It produces a graft copolymer by co-polymerization with another monomer. The process produces a new, polymerizable, optically active polymer and a graft copolymer thereof.

摘要:
A methacrylic ester which functions as the main unit of a polymer or copolymer which is useful as an agent to optically resolve racemic mixtures of compounds.
摘要:
A new organic polymer useful for the optical resolution or solvent fractionation is provided. The organic polymer is a homopolymer or copolymer comprising mainly a specific methacrylate ester constitutional unit and having (+) or (-) optical rotation and, therefore, an optical activity.
摘要:
An object of the present invention is to provide a novel polysaccharide derivative used for a separating agent for optical isomers. The novel polysaccharide derivative contains a structure in which a hydrogen atom of a hydroxyl group or an amino group at 2-position in a structural unit of the polysaccharide is substituted with a monovalent group represented by the following general formula (1), and a hydrogen atom of a hydroxyl group or an amino group at 3-position in the structural unit is substituted with a monovalent group represented by the following general formula (2): R1—NH—CO— (1) R2—NH—CO— (2) where R1 and R2 represent substituted or unsubstituted aryl groups different from each other.
