摘要： The invention provides a method for producing a catalyst for producing polyester by an esterification reaction or a transesterification reaction between a dicarboxylic acid or an ester-forming derivative thereof and a glycol, the method comprising hydrolyzing an organic titanium compound in an organic solvent in which particles of a solid base are dispersed thereby to form a coat layer of titanic acid on the surface of the particles of solid base.According to the invention, the method preferably comprises hydrolyzing an organic silicon compound and/or an organic aluminum compound and/or an organic zirconium compound in an organic solvent in which particles of a solid base are dispersed thereby to form an inner coat layer either of an oxide of at least one element selected from silicon, aluminum and zirconium or of a composite oxide of at least two elements selected from silicon, aluminum and zirconium, and then hydrolyzing an organic titanium compound in the organic solvent in which the particles of a solid base having the inner coat layer thereon are dispersed thereby to form an outer coat layer of titanic acid on the inner coat layer of the particles of a solid base.

摘要： The invention provides a polycondensation catalyst for producing polyester by an esterification reaction or a transesterification reaction between a dicarboxylic acid or an ester-forming derivative thereof and a glycol, the polycondensation catalyst being obtained by hydrolyzing a water soluble titanium compound in the absence of a water soluble alkali in an aqueous slurry in which particles of a solid base are dispersed thereby to form on the surface of the particles of the solid base a coat layer of titanic acid in a content of from 0.1 to 50 parts by weight in terms of TiO2 per 100 parts by weight of the solid base. The invention further provides a method for producing such a polycondensation catalyst, and polyester obtained using such a polycondensation catalyst.
