る。(Means for Solving the Problems) The present invention solves the above problems, and its gist is a polycondensation reaction equipped with a stirrer having a spiral stirring blade with a stirring shaft inserted from above the reactor. A polycondensation reaction device, characterized in that a nozzle mounting port is provided in the upper part of the reactor, and an additive injection nozzle is mounted to the nozzle mounting port with the tip facing the lower part of the stirring shaft. Is.
以下，本考案を図面を参照しながら，具体的に説明す

品取出口を示す。FIG. 1 is an explanatory view showing an example of the apparatus of the present invention, 1 is a reactor, 2 is a main raw material inlet, 3 is a stirring shaft, 4 is a drive motor for the stirrer, 5 is a spiral stirring blade, 6 Is a support of a stirring blade, 7 is a nozzle mounting port, 8 is an additive injection nozzle, and 9 is a product outlet.
添加剤投入ノズル８の先端は，主原料の液面以下で撹拌
軸３の最下部までの位置で撹拌軸の下部方向に向けられ

端の曲げ角度が大きすぎると添加剤が撹拌軸に当たるた
め好ましくない。The tip of the additive injection nozzle 8 is directed toward the lower part of the stirring shaft at a position below the liquid surface of the main raw material to the lowermost part of the stirring shaft 3. If the bending angle of the tip of the additive injection nozzle 8 is too small, the additive hits the stirring blade, so that the object of the present invention cannot be achieved. If the bending angle of the tip of the additive injection nozzle 8 is too large, the additive hits the stirring shaft, which is not preferable.
重縮合反応を実施するに際しては，主原料投入口２から
主原料（モノマー又はオリゴマー）を投入した後，撹拌
しながら，添加剤投入ノズル８から所定量の添加剤を投
入する。When carrying out the polycondensation reaction, the main raw material (monomer or oligomer) is charged from the main raw material charging port 2, and then a predetermined amount of the additive is charged from the additive charging nozzle 8 while stirring.
（考案の効果） 本考案の重縮合反応装置によれば，添加剤投入ノズルの
先端が，撹拌軸の下部方向に向けられているので，投入
