Title (EN) PROCESS FOR PRODUCTION OF ALIPHATIC POLYESTER
(FR) PROCÉDÉ DE FABRICATION DE POLYESTER ALIPHATIQUE
(JA) 脂肪族ポリエステルの製造方法
Abstract: front page image
(EN)Disclosed is a process for producing an aliphatic polyester having good quality continuously and efficiently. Specifically disclosed is a process for producing an aliphatic polyester continuously, which is characterized in that the polyester is produced through a preparation step of preparing a slurry containing an aliphatic dicarboxylic acid and an aliphatic diol, an esterification step, and a polycondensation step. In the process, the slurry in the preparation step has a temperature ranging from the freezing point of the aliphatic diol to 80˚C and a water content of 0.01 to 10 wt%.
(FR)L'invention porte sur un procédé de fabrication en continu et de façon efficace d'un polyester aliphatique de bonne qualité. De façon spécifique, l'invention porte sur un procédé de fabrication en continu d'un polyester aliphatique, lequel procédé est caractérisé en ce que le polyester est produit par une étape de préparation consistant à préparer une bouillie contenant un acide dicarboxylique aliphatique et un diol aliphatique, une étape d'estérification et une étape de polycondensation. Dans le procédé, la bouillie dans l'étape de préparation a une température allant du point de congélation du diol aliphatique à 80°C et une teneur en eau de 0,01 à 10 % en poids.
(JA) 本発明は、品質の良い脂肪族ポリエステルの効率的な連続製造するための方法を提供することを課題とする。本発明は、脂肪族ジカルボン酸と脂肪族ジオールを含むスラリーの調製工程、エステル化反応工程、重縮合反応工程を経てポリエステルを得る脂肪族ポリエステルの連続製造方法において、該調製工程中のスラリーの温度範囲が脂肪族ジオールの凝固点~80°Cで、かつスラリー中の水分量が0.01~10重量%とすることに係わる。
