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.

Abstract: A batch process for preparing polybutylene terephthalate (PBT) includes heating a solid PBT oligomer having an intrinsic viscosity (IV) of 0.1 to 0.2 dL/g and a carboxylic acid end group concentration [CEG] of 90 to 180 mmol/kg at a temperature and pressure defined herein to form melted homogeneous PBT oligomer containing 0 to 300 ppm tetra(C1-C8 alkyl) titanate catalyst, and polycondensing the melted homogeneous PBT oligomer in the presence of a tetra(C1-C8 alkyl) titanate catalyst, reducing the pressure, and maintaining the temperature at approximately 245-260° C. for a sufficient time to provide PBT having an IV of 0.55 and 1.20 dL/g. The PBT oligomer can be prepared by heating a mixture of 1,4-butane diol and purified terephthalic acid in the presence of a tetra(C1-C8 alkyl) titanate catalyst.

The process includes combining 1,4-butane diol and purified terephthalic acid to form a mixture and continuously supplying the mixture to a tower reactor having a plurality of reactor zones for esterification and/or transesterification. The product is continuously supplied to a first continuously stirred tank reactor, and further to a continuous polycondensation reactor. Particular conditions for each step of the process are further described herein. Also disclosed are a device for conducting the process, and a monitoring process for determining the carboxylic acid end group concentration of the resulting PBT.
