축중합 반응성 중합체의 품질을 높게 유지할 수 있는 축중합 반응성 중합체의 제조 방법을 제공한다. 축중합 반응성 중합체를 제조하기 위한 중합기로서, 케이싱과, 그 케이싱 내에 설치된 가이드와, 케이싱에 접속하여 그 하방에 설치된 중합체 배출구를 구비하는 중합기에, 용융 예비 중합체를 공급하는 공정, 및 가이드의 표면에 용융 예비 중합체를 접촉시키면서 유하시켜 상기 용융 예비 중합체를 중합하고, 이에 의해 축중합 반응성 중합체를 제조하는 공정을 갖는 축중합 반응성 중합체의 제조 방법이며, 케이싱의 테이퍼 형상 하부에서의 축중합 반응성 중합체가 유하하는 부분의 투영 면적이 크거나 또는 케이싱의 테이퍼 형상 하부에서의 체류물의 액면이 축중합 반응성 중합체가 유하하는 부분을 많이 포함하도록 제어되는, 제조 방법. A production method for a polycondensation reactive polymer is provided, with which the quality of the polycondensation reactive polymer can be kept high. This production method for the polycondensation reactive polymer is provided with: a step for supplying a molten prepolymer to a polymerization vessel which is for producing the polycondensation reactive polymer, and which is provided with a casing, a guide provided inside the casing, and a polymer discharge port connected to the casing and provided to a lower part of the casing; and a step in which the molten prepolymer is brought into contact with the surface of the guide, made to flow down said surface, and polymerized, and, as a result, the polycondensation reactive polymer is produced. In the production method, either the projected area of a section of a tapered lower part of the casing, said section being where the polycondensation reactive polymer flows down, is large, or the liquid level of a retained substance in the tapered lower part of the casing is controlled so as to include more of the section where the polycondensation reactive polymer flows down.
