Abstract: PROBLEM TO BE SOLVED: To provide a method for continuously polymerizing a polyester, wherein the production efficiency is improved by the optimization of polymerization conditions without improving the basic process or replacing the existing reactor with a highly efficient one. SOLUTION: Provided is a method for continuously producing a polyester by esterifying starting materials being an alkylene terephthalate and/or an isomer thereof and a glycol and/or an esterifiable derivative thereof and polycondensing the obtained polyester oligomer, wherein the terminal carboxyl content of the polyester oligomer fed into the last reactor is 9-30 eq./t.

Abstract: PURPOSE:To prevent the adhesion of granules to the inner wall of a drier by forming a polyester granule path between a rotor and a screen in a fusion preventing device. CONSTITUTION:When polyester granules are loaded from a supply port 1 of a fusion preventing device by a fixing amount, the granules are fed in between a rotor 4 and a screw 7 by a transporting screw 3 that has been previously rotated. The granules are rubbed with each other between the rotor 4 with projection rotating at high speed and the octagonal screen 7. After the surfaces of the granules are crystallized by the rubbing action, the granules are discharged from a discharge port 8. Air from an air supply port 10 is blown from slits through the inside of the screw 3 and the inside of the rotor 4, whereby powder produced by the rubbing action is discharged from a discharge port 11 through slits of the screen 7. Therefore, the fusion of the granules to the inner wall of a drier and to each other can be prevented by their crystallization.

Abstract: PROBLEM TO BE SOLVED: To provide a method that makes it possible to prepare a high-quality polyester consistently, by effectively utilizing waste polyester generated in polyester production steps or the like. SOLUTION: This polyester is prepared by supplying, as raw materials, a dicarboxylic acid and/or an ester forming derivative thereof, as well as a glycol and/or an ester forming derivative thereof, to the ester reaction in order to perform esterification or ester interchange reaction, and then supplying the obtained ester oligomers to the polycondensation reaction in order to perform polycondensation, wherein waste polyester is melted by using a melt extruder, and then the melt is supplied to the ester reaction or the polycondensation reaction in order to produce a polyester polymer.
