| titleOfInvention | Preparation method of copolyester |
| abstract | The invention relates to a method for preparing a copolyester, comprising the steps of: obtaining an oligomer by esterification reaction using 100 mol% of at least one dibasic acid and 100 to 150 mol% of at least one diol as a monomer raw material; The oligomer was subjected to a polymerization reaction in the presence of a titanium phosphorus co-catalyst to obtain the copolyester. Thereby, the prepared copolyester has the characteristics of good hue, improved brightness, and stable production. |
