Zusammenfassung:Disclosed herein is a method for preparing a polycondensation resin. The method includes preparing a low degree condensate; and solid phase polymerizing the low degree condensate, wherein a granular molded article is introduced into the solid phase polymerization. The method enables efficient manufacture of high quality resins without problems such as agglomeration or scaling of a low degree condensate in pipes.
