The present invention provides a catalyst component comprising a vanadium compound supported on a porous polymer having a porosity (mercury) higher than 0.02 cc/g. With the above catalyst components it is possible to prepare elastomeric copolymers of ethylene with .alpha.-olefins CH2=CHR, optionally containing minor proportions of a diene, without fouling problems.
La présente invention concerne un composant catalyseur renfermant un composé vanadium avec comme support un polymère poreux doté d'une porosité (mercure) supérieure à 0,02 cc/g. En faisant intervenir les composants catalyseurs susmentionnés, il est possible d'obtenir des copolymères élastomères d'éthylène avec des .alpha.-oléfines CH¿2?=CHR qui renferment éventuellement de faibles doses d'un diène, sans problèmes de salissure.
