Process for the production of thermoplastic polyester |
| abstract |
The present invention relates to a process for the production of a thermoplastic polyester using a reaction mixture comprising a dicarboxylic acid having a melting temperature of ≥200° C. wherein the dicarboxylic acid is introduced to the process in the form of particles having an average particle diameter of ≥100 μm. Such process results in a reduction of the polymerisation time. Furthermore, it allows for the production of thermoplastic polyesters having a desired balance of intrinsic viscosity and carboxylic end group content at a reduced polymerisation time. |
