Abstract

a. L'invention concerne un procédé pour la fabrication de polyoléfines en poudre utilisables directement dans les machines à extruder ou à injecter, par polymérisation d'éthylène éventuellement en mélange, au moyen de catalyseurs de Ziegler activés. b. On utilise, comme composé vanadyle V, un produit de substitution du chlorure de vanadyle V et d'un alcoolate de vanadyle V ou de ce chlorure avec un alcool, ainsi qu'un composé organique de l'aluminium pour la réduction. c. Ce procédé permet d'obtenir des polyoléfines en poudre qui possedent des propriétés remarquables, au moyen de catalyseurs qui ont une productivité élevée et une longue durée d'efficacité.at. The invention relates to a process for the manufacture of powdered polyolefins which can be used directly in extrusion or injection machines, by polymerization of ethylene optionally as a mixture, by means of activated Ziegler catalysts. b. As the vanadyl compound V, a substitution product of vanadyl chloride V and a vanadyl alcoholate V or this chloride with an alcohol is used, as well as an organic aluminum compound for the reduction. vs. This process makes it possible to obtain powdered polyolefins which possess remarkable properties, by means of catalysts which have high productivity and a long duration of effectiveness.
