摘要： The invention relates to polycarbonates, obtained by reacting a monomer carbonate component with at least one diphenol or dialcohol in the presence of a transesterification catalyst. According to the invention, the melted components are mixed with the transesterification catalyst and a transesterification product is obtained that is then subjected to polycondensation. For polycondensation, the transesterification product is passed through a preliminary reactor, at least one intermediate reactor and a final reactor, said reactors being connected in series and having a shaft, on which mixing elements are attached, that is driven in a substantially horizontal manner. A melt residence time of between 5 minutes and 2 hours is maintained in the preliminary reactor and the final reactor, the temperatures in the preliminary reactor are maintained within the range of 220 to 300 DEG C and the pressure in the preliminary reactor is maintained in the range of 100 to 800 mbar and in the final reactor in the range of 0.1 to 50 mbar.

摘要： According to a method for producing polyesters, the esterification of dicarboxylic acids and diols ensues in at least one reaction stage, the pre-polycondensation of the esterification product ensues in at least one reaction stage, and the polycondensation of the pre-polycondensation product ensues in at least one reaction stage. In order to increase the capacity of a system composed of one or more reaction stages and provided for producing polyesters, the supplied product flow, in at least one of the reaction stages, is split into at least two partial flows before or inside the reaction stage, and the partial flows are guided through the reaction stage while being entirely or partially separated from one another.

摘要： The invention relates to the continuous production of polyesters, whereby the esterification or transesterification of dicarboxylic acids or dicarboxylate diol esters is carried out in at least one reaction stage, the prepolycondensation of the esterification or transesterification product is carried out under vacuum in a reaction stage comprising a vertical tube and the polycondensation of the prepolycondensation product is carried out in at least one reaction stage. According to the invention, the prepolycondensation can be carried out in a reaction stage with simultaneous increase in the viscosity of the prepolycondensation product and lowering of the process temperature, whereby the esterification/transesterification product entering the prepolycondensation reactor, freely moving with limited heating, serially passes through firstly at least one first reaction zone formed from an annular channel, then into a second reaction zone formed in the radially outer annular channel of at least one annular channel divided into several concentric annular channels, then serially through the annular channels to the outlet and is then supplied to a third stirred reaction zone at the base of the vertical tube.

摘要： The invention relates to a method for the production of PBT, whereby a mixture of BDO and TPA are esterified in the presence of a catalyst solution and the esterified product polycondensed. In order to prevent the formation of deposits in the PBT, the catalyst solution contains 0.05 to 10 wt. % alkyl titanate, 85 to 99 wt. % BDO, 50 to 50000 ppm dicarboxylic acids and at most 0.5 wt. % water.

摘要： The invention relates to a method for the production of polyesters or copolyesters, wherein continuos esterification of dicarboxylic acid esters and diols or continuos interesterification of dicarboxylic acid esters with diols is carried out in n reaction pressure levels connected one after the other, wherein the pressure in the first reaction pressure level, which is higher relative to the other reaction pressure levels, drops successively from one reaction pressure level to the other, the vapor flows of the individual reaction pressure levels are jointly rectified in a rectifying column and the diol components falling to the bottom of the rectifying column are fed back again at least to the first reaction level. In order to reduce the degree of complication of said process, at least the last reaction pressure level has a negative pressure, the pressure in the rectifying column is higher than the pressure in the last reaction pressure level and the vapors coming out of the last reaction pressure level are compressed to the pressure prevailing in the rectifying column.
