Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a cyclic polyester oligomer usable as a raw material of a polyester having a high degree of polymerization and a good dyeability, improving its economical properties as compared with the conventional method. SOLUTION: This method for producing the cyclic polyester oligomer is characterized by using an aromatic diacarboxylic acid containing a cationic dye-dyeing site component or its derivative and a diol, or a liner polyester oligomer obtained by an esterification reaction or an ester interchange reaction of an aromatic diacarboxylic acid containing a cationic dye-dyeable site component or its derivative with a diol.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a polyester which has excellent molding processability and can solve problems such as the staining of a spinneret, the elevation of filtration pressure and the breakage of fibers on the production of formed products such as fibers, films or bottles. SOLUTION: This method for producing a polyester comprises subjecting an aromatic dicarboxylic acid or its ester-forming derivative and a diol or its ester-forming derivative to an esterification reaction or a transesterification reaction and then polycondensing the product. Therein, the characteristics comprise using a dinuclear oxide containing titanium and silicon as main metal elements as a polycondensation catalyst and controlling the molar ratio (the molar ratio of the aromatic dicarboxylic acid or its ester-forming derivative to the diol or its ester-forming derivative) of the reaction system to 1.25 to 2.0 when the dinuclear oxide is added.
