Abstract
In the ethylene glycol terephthalate (EGT) polycondensation process, the rate of reaction products removal affects the rate of polycondensation. To investigate this effect further, experiments were carried out with various stirrer speeds under industrial conditions.
The EGT reaction was accelerated very little in the stirrer speed range from 0 to 10rpm, and the optimal speed was found in the range from 40 to 80rpm. The carboxyl end-groups produced by degradation reactions were not affected by stirrer rpm.
