摘要：

The preparation is reported of a new series of chiral polyesters based on mesogenic bis(4-carboxy-phenyl) terephthalate triads and optically active or raceraic 3-O-substituted glycerols. An analysis of the properties in solution and in bulk of the prepared polymers is presented. All the investigated samples exhibit a thermotropic behavior in rather accessible temperature ranges. Cholesteric structures displaying temperature dependent reflection of visible light were evidenced in all the optically active polymers.
