Abstract

Le but proposé dans le titre est atteint par l'adjonction d'un additif qui est mélangé avec une première partie du polymère concerné, dosé et fondu dans une première partie du polymère concerné, dosé et fondu dans une première zone de traitement d'une presse à vis et puis dispersé dans une deuxième zone de traitement avec l'autre partie du polymère aprés le dosage de ce dernier, ou inversement, après quoi le mélange dispersé est, dans une troisième zone de traitement, mis sous dépression et extrudé hors de la presse à vis, et finalement soumis aux traitements conventionnels.The object proposed in the title is achieved by the addition of an additive which is mixed with a first part of the polymer concerned, dosed and melted in a first part of the polymer concerned, dosed and melted in a first treatment zone of a screw press and then dispersed in a second treatment zone with the other part of the polymer after dosing the latter, or vice versa, after which the dispersed mixture is, in a third treatment zone, put under vacuum and extruded out of the screw press, and finally subjected to conventional treatments.
