Abstract

La présente invention a pour objet un procédé de prépara tion de polymères ou de copolymères d' alpha -oléfines faisant appel à un catalyseur perfectionné comprenant un produit solide spécifique associé à un composé organique d'aluminium. L'utilisation de ce produit solide comme constituant cataly tique permet de préparer des polymères ou copolymères d' alpha - oléfines présentant une distribution plus large de masses molé culaires, avec un rendement élevé en polymère.
