摘要

采用界面聚合法制备了含不饱和富马酰氯和柔性皮脂酰氯的7个不同系列的热致性液晶聚酯(TLCPs)。用饱和柔性间隔剂(如皮脂酰氯)制备的均聚酯是亚对称的,而用不饱和脂肪族间隔剂(如富马酰氯)合成的均聚酯是非亚对称的。选择芳香二醇和三醇基介生二醇作为液晶相形成的刚性部分。在每个系列中,通过改变上述两种脂肪族二酸氯化物的相对摩尔比合成共聚酯。大多数液晶聚酯在40°C时与苯酚:四氯乙烷(60:40)具有溶解度。

Thermotropic Liquid Crystalline Polyesters Using Aromatic Rigid Diols, Unsaturated Fumaric Acid and Flexible Sebacic Acid
In the present study, seven different series of thermotropic liquid crystalline polyesters (TLCPs) containing unsaturated fumaroyl chloride and flexible sebacoyl chloride were synthesized using the interfacial polymerization methodology. Homopolyesters prepared with saturated flexible spacer such as sebacoyl chloride were mesomorphic whereas homopolyesters synthesized using unsaturated aliphatic spacer such as fumaroyl chloride that was non-mesomorphic. Aromatic diad and triad based mesogenic diols were selected as rigid moiety for liquid crystalline phase formation. Within each series, copolyesters were synthesized by varying relative mole ratio of the above two aliphatic diacid chlorides. Most of the liquid crystalline polyesters showed solubility in phenol:tetrachloroethane (60:40) at 40 ᵒC.
