According to the invention a new catalyst precursor is obtained, in which alkoxy or siloxy substitution in the 2-position of 5-membered ring of indenyl compound has been carried out. Thereby a metallocene compound is achieved, in which an oxygen atom is directly bonded to the 2-position of a pentahapto indenyl moiety. The catalyst precursors can be used as components for olefin polymerization catalysts.
L'invention concerne un nouveau précurseur de catalyseur, avec un substituant alcoxy ou siloxy en position 2 du cycle indényle à 5 éléments. On obtient ainsi un composé métallocène, dans lequel un atome d'oxygène est directement fixé en position 2 du groupe pentahaptoindényle. Les précurseurs du catalyseur peuvent être utilisés comme composants de catalyseurs de polymérisation d'oléfines.
