由对乙酰氧基苯甲酸、对苯二酚二乙酯、2,6-萘二甲酸及间苯二甲酸四种单体通过熔融缩聚反应,合成了全芳香族四组分共聚酯。在一定的组成范围内,共聚酯熔体有很好的液晶性。本文重点讨论了聚合物的组成与性质的关系,热谱特征和液晶相行为。
From the acetoxybenzoic acid, hydroquinone diethyl ester, 2,6-naphthalene dicarboxylic acid and isophthalic acid four kinds of monomers through the melt polycondensation reaction, the synthesis of all aromatic four component copolyester. In a certain range of composition, copolyester melt has good liquid crystallinity. This article focuses on the polymer composition and properties of the relationship between the thermal characteristics and the liquid crystal phase behavior.
