| titleOfInvention | Polyester production method |
| abstract | (57) [Summary] [Constitution] When a polyester is produced by polycondensing an aromatic dicarboxylic acid or an ester-forming derivative thereof and an aliphatic diol or an ester-forming derivative thereof in the presence of a polycondensation catalyst, A method for producing a polyester, comprising using a catalyst comprising a (I) germanium compound and ( II) an alkali metal compound as a polycondensation catalyst. The polycondensation reaction can be completed in a shorter time than when a germanium compound catalyst is used alone. Further, since the amount of the germanium compound used as the catalyst can be reduced, the production cost of the polyester can be reduced. |
