Synthesis and Radical Polymerizations of N-Substituted Maleimide Bearing Two Olefinic Groups

Abstract

A kind of N-substituted maleimide - having two olefinic bonds with different reactivities, (S)-N-Maleoyl-L-leucine allyl ester ((S)-ALMI), was synthesized from maleic anhydride, L-leucine and allyl alcohol. Radical polymerizations were carried out to obtain optically active polymers using 2,2′-azobisisobutyronitrile. Structures of the monomer and polymers obtained were investigated by NMR measurements. In radical polymerizations, the solvents strongly affect the radical polymerization behaviors of (S)-ALMI.
