Abstract

La présente invention concerne un dispositif de préparation de polyesters thermoplastiques, en particulier de téréphtalate de polyéthylène, et de polyamides thermoplastiques, en particulier de polyamide 6, par polycondensation continue en phase solide en lit mobile. Selon ce procédé, on place à l'intérieur d'un réacteur tunnel vertical des structures ou tissus à mailles horizontaux, perpendiculairement à la paroi du réacteur. On obtient des particules polymères de bonne qualité, ne s'agglutinant pas.The present invention relates to a device for preparing thermoplastic polyesters, in particular polyethylene terephthalate, and thermoplastic polyamides, in particular polyamide 6, by continuous polycondensation in solid phase in a moving bed. According to this process, horizontal mesh structures or fabrics are placed inside a vertical tunnel reactor, perpendicular to the wall of the reactor. Good quality polymer particles are obtained which do not clump together.
