采用１３Ｃ－ＮＭＲ，ＩＲ及ＷＡＸＳ表征了甲基丙烯酸三苯基甲酯（ＴｒＭＡ）与甲基丙烯酸甲酯（ＭＭＡ）光学活性共聚物结构．阐明了具有单向螺旋链的光学活性共聚物组成的非均一性及其光学活性随组成变化呈ｓ型曲线的特征．
The structures of the optically active copolymers of triphenylmethyl methacrylate (TrMA) and methyl methacrylate (MMA) were characterized by13C-NMR, IR and WAXS. The heterogeneity and the optical activity of the optically active copolymer with unidirectional helical chains were characterized by the s-type curve.
