METHOD FOR PRODUCING POLYESTER, AND FLUORINE-CONTAINING DICARBOXYLIC ACID ESTER COMPOUND

摘要

The present invention relates to a method for producing a polyester, containing conducting a transesterification reaction of at least one compound selected itOtri5 compounds represented by the following formulae (1) to (3) with a diol compound in the presence of a catalyst:[Chem. I]71 V H , V HIF21 II112—y-01—N-1-01—R- n2—c—o—c—Ar—c—o——cF2 FA——0—C—At—C-04—cFaR3 0 0 R3 R3 8 8 F2&—17 H 8 8 F2c—A7co (2) (3)10 wherein Ar is a divalent aromatic hydrocarbon group or the like; 121 is CX1Y1R4; R2 is a hydrogen atom or CX2Y2R6; R.3 is a hydrogen atom or CX3Y3R6;12.2 is a perfluoroalkylene group having 1 to 5 carbon atoms; X1 to X3 are a hydrogen atom, a fluorine atom or RI; Y1 to Y3 are a fluorine atom or R."; R4 to R6 are a fluorine atom, Rf, ORf or the like; and RI is a fluoroalkyl group having 1 to 4 carbon atoms.
