Abstract
(DE)
Verfahren zur Entfernung von Styrol-Restmonomeren aus Polystyrol und wasserunlösliches, vernetztes Polyvinylpyrrolidon enthaltenden Blends durch Behandlung mit Wasser, dadurch gekennzeichnet, dass die Behandlung an einem teilchenförmigen festen Blend erfolgt.
(EN)
The invention relates to a method for removing styrene residual monomers from polystyrene and from blends containing water-insoluble cross-linked polyvinyl pyrrolidone by treating with water. The invention is characterized in that the treatment is carried out on a particle-shaped solid blend.
(FR)
L'invention concerne un procédé d'extraction de monomères résiduels de styrol à partir de mélanges contenant du polystyrol et une polyvinypyrrolidone réticulée insoluble dans l'eau, par traitement avec de l'eau, caractérisé en ce que le traitement est effectué sur un mélange solide particulaire.
