摘　　要：利用溶胶-凝胶合成非晶态技术,将手性分子灰黄霉素(C17H17ClO6)均匀地掺入到甲基丙烯酸甲脂(MMA)溶胶-凝胶体系中,成功地研制出长5 cm的聚甲基丙烯酸甲酯(PMMA)手性凝胶块体,测量了它的偏振响应.用自制的实验测试装置测量了3根总长为15 cm PMMA手性凝胶块体的旋光色散特性,发现在450～700 nm的波长范围内其结果与玻耳兹曼公式拟合的结果基本符合,手性PMMA块体在450 nm时的旋光角为69°,在700 nm时的旋光角为17°.Ohiral molecule C17H17ClO6 was incorporated in methl methacrylate（MMA） by sol-gel process. Its optical polarization response has been measured. We also measured the optical rotatory dispersion by self-manufactured apparatus. It is found that the maximum and minimum rotation angle of the chiral polymethyl methacrylate（PMMA） are 69° at the wavelength of 450 nm and 17° at the wavelength of 700 nm, respectively. The results of the experiment accord with that simulated by the Boltzmann formula.
