| abstract | [PROBLEMS] To reduce the occurrence of foreign matters due to polymerization catalysts and hue modifiers and mold stains during molding, improve the thermal stability and hue of polymers compared to conventional products, and improve hue deterioration when melted at high temperatures. A method for producing polyester is provided. Titanium prepared as an alkylene glycol solution satisfying the formulas (1) and (2) in a method for producing a polyester by esterification or transesterification and then polycondensation reaction under reduced pressure in a polymerization reactor Add a compound and a color modifier adjusted as an alkylene glycol solution satisfying formulas (3) and (4) until the polyester reaches the target degree of polymerization, and start depressurizing the phosphorus compound in the polymerization reactor. And then the polyester is added until the polyester reaches the target degree of polymerization. (1) 0.1 ≦ T / W T ≦ 1.5 (2) 0.01 ≦ W T ≦ 1.0 (3) 0.01 ≦ C / W C ≦ 1.0 (4) 0.01 ≦ W C ≦ 1.0 [T: Titanium atom concentration (wt%) in solution, W T : Water content (wt%) in the solution, C: Hue adjusting agent concentration (wt%) in the solution, W C : Moisture in the solution Amount (% by weight)] [Selection figure] None |
