| 摘 要： | In this paper,(-) menthyl methacrylate(-) MnMA) was polymerized at -78℃ in toluene with three types of anionic catalysts, which were complexes of fluorenyllithium with (-) sparteine-((-)-Sp),(S,S)-( )-2,3-dimethoxy-1,4-bis(dimethylamino) butane( )DDB) and N,N,N,N′-tetra-methylethylenediamine(TMEDA), and the chiral optical property of the obtained polymer was studied. The circular dichroism (CD) spectrum of the polymer showed negative Cotton effect.

| Abstract: | In this paper, (-)menthyl methacrylate((-)MnMA) was polymerized at 78C in toluene with three types of anionic catalysts, which were complexes of fluorenyllithium with (-)sparteine - ((-)-Sp) , (S, S)-(+)-2, 3-dimethoxy-1, 4-bis(dimethylamino)butane((+)DDB) and N,N,N,N-tetra- methylethylenediamine(TMEDA), and the chiral optical property of the obtained polymer was studied. The circular dichroism (CD) spectrum of the polymer showed negative Cotton effect. |
