Abstract

Procedimento per la preparazione di copolimeri elastomerici dell'etilene con alfa olefine CH2 = CHR, contenenti eventualmente proporzioni minori di un diene caratterizzato dall'impiego, nel corso della polimerizzazione, di un catalizzatore comprendente il prodotto della reazione tra:(I) un componente solido comprendente VCl3, supportato su dialogenuro di magnesio sferico o sferoidale in forma attiva (II) un composto alluminio alchilico (III) eventualmente un idrocarburo alogenato.VCl3 viene precipitato sul dialogenuro di magnesio mediante riscaldamento di soluzioni di VCl4 in solventi idrocarburici inerti.
