Optical resolution ability of optically active poly(N-diphenylmethyl maleimide)

A new optically active polymer, (+)poly(N-diphenylmethyl maleimide), was coated on macroporous silica gel and used as a chiral stationary phase for high performance liquid Chromatographic resolution of enantiomers. The chiral polymer showed efficient resolution ability to some polar racemates, and eleven pairs of racemates are resolved effectively.
