Abstract

PURPOSE: An apparatus for polycondensation which is designed to keep the residence time of the reaction liquid constant and prevent the degradation of product quality with the help of agitating blades which are attached to the shaft radially in such a way as to make the respective phase angles advance at a uniform differential modulation from the inlet for the reaction liquid toward the outlet.
