| titleOfInvention | Method for producing polyester resin composition and film obtained therefrom |
| abstract | An object of the present invention is to provide a method for producing a polyethylene naphthalate resin composition having both excellent fusion heat stability and excellent polymer hue and transparency, and to provide a film obtained therefrom. After the transesterification reaction with a transesterification catalyst is completed, a specific phosphorus compound A is added at a ratio of the formula (1) to lose the activity of the transesterification catalyst, and then a titanium compound is used as a polymerization catalyst. A method for producing a polyester resin composition, wherein a polycondensation reaction is completed by adding a phosphonate compound, which is a phosphorus compound B, at a ratio of the formula (2). 0.4 ≦ Pa / M ≦ 0.8 (1) 0.8 <(Pa + Pb) /M≦1.4 (2) (Pa is the molar concentration of the phosphorus element in the phosphorus compound A, M is the metal element of the transesterification catalyst, and Pb is the molar concentration of the phosphorus element in the phosphorus compound B with respect to all dicarboxylic acid components.)
