Process and apparatus for producing polyesters, copolyesters and polycarbonates |
| abstract |
In a process of producing polyesters, the esterification of dicarboxylic acids and diols is effected in at least one reaction stage, the pre-polycondensation of the esterification product is effected in at least one reaction stage, and the polycondensation of the pre-polycondensation product is effected in at least one reaction stage. To increase the capacity of a plant for producing polyesters, which is formed of a plurality of reaction stages, it is provided that in at least one of the reaction stages the product stream supplied is divided in at least two partial streams before or inside the reaction stage, and the partial streams are passed through the reaction stage wholly or partly separate from each other. |
