Abstract:
The present invention relates to a method for producing a polyester, containing conducting a transesterification reaction of at least one compound selected from compounds represented by the following formulae (1) to (3) with a diol compound in the presence of a catalyst: wherein Ar is a divalent aromatic hydrocarbon group or the like; R1 is CX1Y1R4; R2 is a hydrogen atom or CX2Y2R5; R3 is a hydrogen atom or CX3Y3R6; R7 is a perfluoroalkylene group having 1 to 5 carbon atoms; X1 to X3 are a hydrogen atom, a fluorine atom or Rf; Y1 to Y3 are a fluorine atom or Rf; R4 to R6 are a fluorine atom, Rf, ORf or the like; and Rf is a fluoroalkyl group having 1 to 4 carbon atoms.
