Title:
POLYMER OF OPTICALLY ACTIVE NORBORNENE DERIVATIVE AND OPTICAL RESOLUTION AGENT
Document Type and Number:
Japanese Patent JP3403469
Kind Code:
B2
Abstract:
PURPOSE: To provide a polymer of an optically active norbornene derivative having optical rotatory power and useful as a resolution agent for optical isomer and geometric isomer.
CONSTITUTION: A polymer of an optically active norbornene derivative of the formula I or the formula II (R1 and R2 are 6-30C aromatic or substituted aromatic group) and having a degree of polymerization of ≥5. The polymer can be produced by polymerizing an optically active norbornene derivative of the formula III or the formula IV in the presence of a transition metal catalyst (e.g. WCl6-ph4Sn) in a solvent (e.g. benzene) at -98 to +120°C. The optical resolution agent composed of the polymer has excellent optical resolution discrimination capacity and is effective the optical resolution of a wide range of compounds.
