Definitions

  • the standing time is preferably 8 hours or more, more preferably 12 hours or more, and further preferably 24 hours or more, from the viewpoint of sufficient consumption of the lactam compound.
  • the standing time is preferably 120 hours or less, more preferably 96 hours or less, and even more preferably 72 hours or less, from the viewpoint of suppressing a decrease in polyamide productivity.
  • the standing time varies depending on the type of lactam compound and the resulting polyamide, and can be appropriately adjusted depending on the standing temperature described below.

Abstract

La présente invention réalise un procédé de fabrication de polyamide qui permet de fabriquer facilement et en continu des polyamides. Les Polyamides sont fabriqués en fournissant en continu une composition de matière première à partir d'un orifice d'alimentation (2) d'un dispositif de réaction continue ayant un seul cylindre (1), et en déchargeant en continu un produit à partir d'un orifice de décharge (3). Dans le cylindre (1), la composition de matière première, qui est à l'état liquide et contient un composé de lactame, est agitée à pression atmosphérique et transportée, et à ce stade, le composé de lactame subit une polymérisation par ouverture de cycle, générant ainsi des polyamides solides.
