Abstract: Disclosed is a continuous process and device for making polybutylene terephthalate (PBT) resin, particularly high molecular weight PBT resin. 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.

Abstract: A process for the manufacture of polycarbonate particles is disclosed herein. The process includes combining a first solution including a polycarbonate and a phosphorus-containing flame retardant or a flame retardant polycarbonate, and an organic solvent with a second solution including a surfactant and an aqueous solvent substantially immiscible with the organic solvent, under conditions of shear and temperature effective to provide an emulsion. At least a portion of the organic solvent is removed from the emulsion to provide an aqueous slurry having a plurality of particles, wherein the particles include the polycarbonate and the phosphorus-containing flame retardant or the flame retardant polycarbonate.
