Abstract
PURPOSE: To obtain a polyester having a high softening point and good color tone, by polycondensation reaction of a glycol ester of a bifunctional aromatic carboxylic acid, using the reaction product of a titanium and a phosphorus compounds as a catalyst.
CONSTITUTION: The reaction product of a titanium compound shown by formula Ti(OR)4 (R is alkyl) and a phosphorus compound shown by formula R1 OP(OR2) (O)OR3[R1, R2, and R3 are H or alkyl, at least one of the R1, R2 and R3 is alkyl] is used as a polycondensation catalyst 1n the production of a polyester obtained by the polycondensation of a glycol ester of a bifunctional carboxylic acid and/or its oligomer. Tetrapropyl, or tetrabutyl titanate, etc. may be cited as the titanium compound. A mono- or dialkyl ester of phosphoric acid, etc. may be cited as the phosphorus compound.
