全芳香族热致性液晶聚酯具有高强度高模量优越性能,近年来在国内外受到重视。2,6-取代的萘环结构引入全芳香族聚酯主链后可提高聚合物的液晶性和热稳定性,且能一定程度地降低聚合物的熔融温度,便于成型加工。2,6-萘二甲酰氯是合成这类聚芳酯的常用单体, All aromatic thermotropic liquid crystal polyester with high strength and high modulus superior performance, in recent years at home and abroad have received great attention. The 2,6-substituted naphthalene ring structure can improve the liquid crystallinity and thermal stability of the polymer after the introduction of the wholly aromatic polyester backbone, and can reduce the melting temperature of the polymer to a certain extent and facilitate the molding process. 2,6-naphthalene dichloride is a common monomer for the synthesis of such polyarylates,
