Beschreibung
Zusammenfassung:	This invention relates to the field of olefin polymerization catalyst compositions, and methods for the polymerization and copolymerization of olefins, typically using a supported catalyst composition. In one aspect, this invention encompasses precontacting a metallocene with an olefin or alkyne monomer and an organoaluminum compound, prior to contacting this mixture with the acidic activator-support. Cette invention concerne le domaine des compositions de catalyseurs de polymérisation d'oléfines et des procédés de polymérisation et de copolymérisation d'oléfines utilisant typiquement une composition de catalyseur sur support. Dans un aspect, cette invention consiste à mettre en contact préalable un métallocène avec un monomère d'oléfines ou d'alkyne et un composé d'organoaluminium, avant de mettre ce mélange en contact avec l'activateur acide-support.
