| abstract |
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. |
