| titleOfInvention | Polyester manufacturing method |
| abstract | (57) [Summary] [PROBLEMS] To provide a method for producing a polyester which is excellent in color tone and thermal stability, has good moldability such as spinning and drawing, and has very little foreign matter attached to a spinneret. A glycol ester of a bifunctional carboxylic acid comprising a bifunctional carboxylic acid component mainly containing a bifunctional aromatic carboxylic acid and / or an ester-forming derivative thereof and a diol component mainly containing alkylene glycol, and / Alternatively, when a low polymer thereof is subjected to a polycondensation reaction to produce a polyester, a polyphosphoric acid compound is added in an amount of 5 to 100 mmol with respect to the difunctional carboxylic acid component, and the polyphosphoric acid compound is substantially non-reactive with the polyester. The organic sulfonate is added in an amount of 0.001 to 0.5% by weight based on the polyester. |
