  The problem to be solved by the present invention is to provide a method for continuously and effectively producing an aliphatic polyester having an increased molecular weight which prevents evaporation of diisocyanate at the step of mixing the diisocyanate with the aliphatic polyester prepolymer in a molten state at a temperature not lower than the melting point of the prepolymer and enables uniform mixing of the diisocyanate with the aliphatic polyester prepolymer. In order to solve this problem, the present invention provides a method for producing an aliphatic polyester having an increased molecular weight comprising the steps of: (i) quantitatively injecting a diisocyanate into an aliphatic polyester prepolymer which has a number average molecular weight of 5000 or higher and has terminal hydroxyl groups and in which at least one acid component is a succinic acid compound, in a molten state at a temperature not lower than the melting point thereof, wherein the amount of diisocyanate is equivalent to between one tenth and two times the amount of the hydroxyl groups in the aliphatic polyester prepolymer, (ii) quantitatively and continuously mixing the diisocyanate-containing aliphatic polyester prepolymer obtained at step (i) by a static mixer, discharging same from the static mixer, and then supplying same to a coupling reaction tank, and (iii) reacting the aliphatic polyester prepolymer with the diisocyanate in the coupling reaction tank.

  本发明要解决的问题是提供一种连续有效地生产分子量增大的脂肪族聚酯的方法，该方法可防止二异氰酸酯与脂肪族聚酯预聚物在不低于预聚物熔点的温度下以熔融状态混合时的二异氰酸酯蒸发，并可使二异氰酸酯与脂肪族聚酯预聚物均匀混合。为了解决这个问题，本发明提供了一种生产分子量增大的脂肪族聚酯的方法，包括以下步骤： (i) 将二异氰酸酯定量注入脂肪族聚酯预聚物中，该预聚物的平均分子量为 5000 或更高，且具有末端羟基，其中至少一种酸组分为琥珀酸化合物。 二异氰酸酯的量相当于脂肪族聚酯预聚物中羟基量的十分之一到两倍、 (ii) 通过静态混合器定量、连续地混合步骤(i)中得到的含二异氰酸酯的脂肪族聚酯预聚物，将其从静态混合器中排出，然后将其供应到偶联反应罐中，以及 (iii) 在偶联反应罐中使脂肪族聚酯预聚物与二异氰酸酯反应。

  The present invention addresses the problem of providing a method for continuously and effectively producing an aliphatic polyester having an increased molecular weight by preventing evaporation of a diisocyanate when blending the diisocyanate with an aliphatic polyester prepolymer in a molten state at a temperature not lower than the melting point thereof so that the diisocyanate and the aliphatic polyester prepolymer are uniformly blended. In order to solve the above-mentioned problem, the present invention provides a method for producing an aliphatic polyester having an increased molecular weight comprising the steps of (i) quantitatively injecting a diisocyanate into an aliphatic polyester prepolymer which has a number average molecular weight of 5,000 or higher and has terminal hydroxyl groups and in which at least one acid component is a succinic acid compound, in a melting state at a temperature not lower than the melting point thereof wherein the amount of the diisocyanate is equivalent to between one tenth and two times the amount of hydroxyl groups in the aliphatic polyester prepolymer, (ii) quantitatively and continuously introducing the diisocyanate-containing aliphatic polyester prepolymer obtained at the step (i) into a mixing tank, discharging same from the mixing tank under stirring and supplying it to a coupling reaction tank, and (iii) reacting the aliphatic polyester prepolymer with the diisocyanate in the coupling reaction tank.
