Abstract

Catalyseur pour la polymérisation d'oléfilnes-1, obtenu par modification d'un halogénure de magnésium avec un donneur d'électrons et/ou un cyclopolyène, lavage avec un hydrocarbure, mise en contact avec un halogénure de titane, puis broyage de la composante ainsi obtenue avec un composé alumino-organique et avec un stéréorégulateur. Ce catalyseur permet d'obtenir des polyoléfines ayant une grande isotacticité et une faible proportion de particules très fines, avec de bons rendements.
