Abstract

L'invention concerne les catalyseurs. Il s'agit d'un procédé pour la préparation d'un catalyseur de polymérisation d'oléfines comprenant la réduction de TiCl4 avec un composé organo-aluminium en présence d'un oxyde d'alcoyle, caractérisé en ce que TiCl4 est réduit avec un composé aluminium-trihydrocarbyle dans un rapport molaire Ti : Al compris entre 2,7 : 1 et 4 :1 en présence d'oxyde d'isoamyle et d'un solvant hydrocarboné par addition progressive de TiCl4 au composé aluminium-trihydrocarbyle à une température comprise entre 15 et 50 degrés C pendant une période comprise entre 0,7 et 2,5 heures de manière à produire un précipité de TiCl3 , après quoi ce précipité est transformé en TiCl3 actif par chauffage à une température comprise entre 80 et 110 degrés C pendant au moins 30 minutes. Ce catalyseur permet d'obtenir des catalyseurs à activités améliorées.
