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.

A novel type of chiral N-substituted methacrylamide derivatives bearing an oxazoline pendant (OPMAM) had been synthesized. Radical polymerization were carried out to produced corresponding polymers with high specific rotation in moderate yields. The polymerization characteristics and the chiroptical behavior of the resultant polymers have been examined in detail by using HPLC and CD and UV-vis spectra. The polymers showed relatively high molecular weights(Mn=5000-15000). The abolutely value of the specific rotation of poly(OPMAM)s basically increased with increasing the molecular weights.

The radical polymerization of a novel methacrylamide derivative, N-[o-(4-ethyl-4, 5-dihydro-1, 3-oxazol-2-yl) phenyl] methacrylamide ((S)-EtOPMAM), was carried out to obtained optically active polymers. The polymer yield and the chiroptical behavior of the resultant polymers have been examined in detail by using IR and 1H NMR spectroscopies in comparison with our previous observation. The polymers showed relatively high molecular weights (Mn=8000-16000) and largest specific rotations ([α]25D =+120.6o). Particularly, the largest specific optical rotation of the polymer is almost the six times of the monomer.
