甲基丙烯酸三苯基甲酯与甲基丙烯酸甲酯光学活性共聚物的结构特征

STRUCTURE CHARACTERIZATION OF OPTICALLY ACTIVE COPOLYMERS OF TRIPHENYLMETHYL METHACRYLATE AND METHYL METHACRYLATE

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．

he structure of Optically active Copolymers of triphenylmethyl methacrylate (TrMA) with methyl methacrylate (MMA) has been studied by 13C-NMR.IR, UV and WAXS. The Compositional heterogenity of the Optically active copolymers having one-handed helicity was found and the Change of specific rotation of Copolymers with TrMA unit Content in Copolymers Showed a S-curve relationship.
