通过对-乙酰氧基苯甲酸或对-乙酰胺基苯甲酸和聚酯-聚醚多嵌段共聚物的硬段PET进行酸解反应,和随后的乙酰氧基或乙酰胺基,和羧基间的缩聚反应,分别合成了硬段含介晶的共聚酯-聚醚多嵌段共聚物和聚酯酰胺-聚醚多嵌段共聚物,研究了它们的热致液晶行为。
By acid hydrolysis of the hard segment PET of para-acetoxybenzoic acid or para-acetamidobenzoic acid and of the polyester-polyether block copolymer and subsequent acetoxy or acetamide groups and between the carboxyl groups , Respectively, and the hard segment mesogen-containing copolyester-polyether block copolymers and polyesteramide-polyether block copolymers were synthesized respectively and their thermotropic liquid crystal behavior was also studied.
