METHOD FOR ADDING RAW MATERIALS DURING THE PRODUCTION OF POLYESTERS OR COPOLYESTERS

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.
