| titleOfInvention | Method for producing polyethylene terephthalate |
| abstract | The object of the present invention is to provide polyethylene that can significantly improve only the col-b value without affecting the col-a value, col-L value, thermal stability, polymerization reactivity, moldability, etc. The object is to provide a method for producing terephthalate. The object is a method for producing polyethylene terephthalate comprising a transesterification reaction step and a melt polycondensation reaction step, Dimethyl terephthalate, ethylene glycol is used as a raw material, and at least one compound selected from titanium compound a is used as a transesterification catalyst to perform a transesterification reaction step, and is selected from the group consisting of germanium compound, titanium compound b, and antimony compound. Using at least one compound as a polycondensation catalyst, adding at least one compound selected from the group consisting of dibutyl phosphate, terephthalic acid and an alkali metal compound or an alkaline earth metal compound to perform a melt polycondensation reaction step It can be solved by a method for producing polyethylene terephthalate characterized by the following. [Selection figure] None |
