Abstract

Disclosed is a method for obtaining a polyester wherein a dicarboxylic acid or an ester-forming derivative thereof and a diol or an ester-forming derivative thereof are esterified or transesterified, and then the resulting product is polycondensed in the presence of a titanium polycondensation catalyst. In this method, generation of extraneous material caused by the catalyst and mold contamination during molding can be reduced by adding a phosphorus compound having a specific structure, and thus there can be obtained a polyester which is remarkably improved in thermal stability and color tone of the polymer when compared with the conventional polyesters.
