摘要：
The invention relates to a method for producing polyesters or copolyesters without using a balance to dose the solid main raw material dicarboxylic acid, and to a corresponding concept for regulating the molar ratio of the paste prepared from the starting materials, without directly measuring the rate of flow of the solid main raw material dicarboxylic acid by weighing. The invention also relates to an indirect method for determining the raw material consumption without directly weighing the solid raw material. The regulation of the addition rate of the solid raw material is carried out on the basis of the deviation of the density of the finished paste from a solvent.
