Abstract
PURPOSE: The polycondensation of polyester monomers is conducted under the number of rotation of the metering pump controlled by forecasting of the monomer amount supplied into the reactors thereby the liquid level in the final reactor is kept constant and polyesters of consistent quality are produced in high efficiency.
