    Abstract: PURPOSE:A polyester that is composed of two kinds of specific structure units, thus being melt-formable, having good flame, retardancy, chemical resistance and wear resistance and moreover, showing outstanding mechanical properties and heat resistance. CONSTITUTION:A fluorine-containing copolyester is composed of 30-90mol% of formula I units and 70-10mol% of formula II units. The copolymer is preferably prepared using 4-hydroxybenzoic acid and 4-hydroxy-2,3,5,6- tetrafluorobenzoic acid by deacetoxylation. The ratio of I/II is preferably 40/60-90/10, and the polymerization degree is over 100.
