(FR) PROCEDE ET APPAREIL DE FRACTIONNEMENT TECHNIQUE D'OLIGOMERES ET DE POLYMERES
Abstract: front page image
(EN)Spinning Process and Apparatus for the technical fractionation of oligomers and polymers. Process for the fractionation of polymers, characterized in that a polymer solution (delivering-phase) is pressed through one or more spinning nozzles into an intensively agitated precipitation liquid (receiving-phase), wherein a two-phase mixture of a sol-phase and a gel-phase is formed, and the sol-phase and the gel-phase are separated from each other.
(FR)La présente invention concerne un procédé de fractionnement de polymères. Ce procédé est caractérisé en ce qu'il consiste à comprimer une solution polymère (phase de distribution) à travers une ou plusieurs buses rotatives dans un liquide de précipitation intensément agité (phase de réception), afin de former un mélange à deux phases, constitué d'une phase sol et d'une phase gel, puis à séparer la phase sol et la phase gel l'une de l'autre.
