OPTICALLY ACTIVE POLYMALEIMIDE DERIVATIVE, METHOD FOR PRODUCING THE SAME, OPTICAL RESOLUTION AGENT CONSISTING OF THE SAME AND METHOD FOR RESOLUTION OF OPTICALLY ACTIVE COMPOUND USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a new optically active polymer useful as an optical resolution agent. SOLUTION: This new polymer, an optically active polymaleimide derivative having an optical rotation of >=190 deg. is obtained by anionic polymerization of the corresponding melamine derivative in the presence of an optically active ligand. The new optically active polymer thus obtained is used as an optical resolution agent.
