Process for the production of polyesters |
| abstract |
This invention relates to a process for the production of polyesters comprising an esterification/transesterification stage and a polycondensation stage, characterized in that the said polycondensation stage is carried out in the presence of a catalyst comprising a mixture of at least one Titanium-based compound and at least one Zirconium-based compound in which the Ti/(Ti+Zr) ratio by weight is equal to or greater than 0.01 and equal to or less than 0.40. |
