4-Hydroxy-2,3,5,6-tetrafluorobenzoic acid/6-hydroxy-2-naphthoic acid copolymers (FHBA/HNA copolymer) with different copolymer compositions were prepared and the influence of FHBA residue on the thermal properties and structures of the copolymers were investigated. Introduction of FHBA decreased the
## Abstract A series of fully aromatic copolyesters based on __p__βacetoxybenzoic acid (__p__βABA), hydroquinone diacetate (HQDA), terephthalic acid (TPA), and __m__βacetoxybenzoic acid (__m__βABA) were prepared by a modified meltβpolycondensation reaction. The copolyesters were prepared in two ser
