Abstract
(DE)
Es wird ein Verfahren zur Oberflächenmodifizierung von Formkörpern offenbart, bei dem man die Formkörper mit ethylenisch ungesättigten Monomeren pfropft. Auf der Oberfläche eines Formkörpers aus einem ersten Polymer wird eine Schicht eines zweiten Polymers gebildet. Anschließend bildet man auf der Schicht des zweiten Polymers ein drittes Polymer, indem man auf die Schicht des zweiten Polymers mindestens ein ethylenisch ungesättigtes Monomer aufpfropft. Die Erfindung ermöglicht es u.a., die Pfropfung auf die Schicht des zweiten Polymeren zu begrenzen, ohne daß das erste Polymer durch Einlagerung vom Pfropfpolymer eine nachteilige Veränderung erfährt. Die erfindungsgemäß hergestellten gepfropften Formkörper können u.a. in Trennverfahren nach dem Prinzip der adsorptiven Stofftrennung eingesetzt werden.
(EN)
In a process for modifying the surface of mouldings, the mouldings are grafted with ethylenically unsaturated monomers. A layer of a second polymer is formed on the surface of the moulding, which is made of a first polymer. A third polymer is then formed on the layer of the second polymer by grafting at least one ethylenically unsaturated monomer onto the layer of the second polymer. The invention makes it possible, amongst other things, to limit the grafting to the layer of the second polymer without the first polymer being adversely affected by the intercalation of the graft polymer. The grafted mouldings of the invention can be used, amongst other things, in a separation process based on the principle of adsorptive separation of substances.

Selon un procédé de modification de la surface d'objets moulés, on greffe sur les objets moulés des monomères éthyléniquement insaturés. On forme sur la surface d'un objet moulé en un premier polymère une couche en un deuxième polymère. Ensuite on forme sur la couche composée du deuxième polymère un troisième polymère en greffant sur la couche composée du deuxième polymère au moins un monomère éthyléniquement insaturé. On peut ainsi, parmi d'autres avantages, limiter le greffage à la couche composée du deuxième polymère sans affecter négativement le premier polymère par déposition du polymère greffé. On peut utiliser les objets moulés greffés selon ce procédé par exemple pour mettre des procédés de séparation selon le principe de la séparation de substances par adsorption.
