对基于Ｌ（＋）酒石酸二乙酯和邻、间、对位苯二甲酰氯的光学活性聚酯进行了合成．这类聚酯的比旋光度与所采用的二酰氯有关，依次为对苯＞间苯＞邻苯．通过模型化合物、最小能量优化及圆二色谱等分析表征阐明了这类聚酯不同的结构形态特征． Synthesis of optically active polyesters based on L  (+)  diethyl tartrate and o-, m- and p-phthaloyl dichlorides was studied. The specific rotation of these polyesters and diacid chloride used, followed by benzene> m-benzene> o-benzene. Through the model compounds, the minimum energy optimization and circular dichroism and other analytical characterization to clarify the different structural features of this type of polyester.
