Abstract
(EN)
Reactivated unsupported catalyst compositions methods of using them are disclosed whereby the compositions have concentration of preactivated catalyst of at least about 0.04 mmol of preactivated catalyst per liter of solution when using aliphatic or alicyclic hydrocarbon solvents, and a concentration of less than about 0.80 mmol/liter when using aromatic or halogen-substituted solvents. In the method, an unsupported catalyst precursor first is contracted with an activator, or co-catalyst, in a suitable reaction medium, and then the resulting mixture is contacted with additional solvent to form a preactivated unsupported olefin polymerization catalyst composition that can be fed to a gas phase polymerization reactor without plugging the catalyst injection nozzle. Combining the unsupported catalyst precursor, the co-catalyst and then adding additional solvent to provide such a composition prevents tube plugging, and provides a catalyst material that has high activity, avoids forming significant amounts of polymer agglomerates, and avoids reactor fouling.

L'invention concerne des compositions de catalyseurs non supportés pré-activés et leurs procédés d'utilisation, la concentration de catalyseurs pré-activés dans les compositions étant d'au moins 0,04 mmoles environ de catalyseurs pré-activés par litre de solution lorsque des solvants hydrocarbonés aliphatiques ou alicycliques sont utilisés, et la concentration étant inférieure à environ 0,80 mmoles/litre lorsqu'on utilise des solvants aromatiques ou substitués par des halogènes. Le procédé selon l'invention consiste à mettre en contact un précurseur de catalyseur non supporté d'abord avec un activateur ou un co-catalyseur dans un milieu de réaction approprié, puis de mettre en contact le mélange obtenu avec un solvant supplémentaire pour former une composition de catalyseur de polymérisation d'oléfines non supporté pré-activé pouvant être introduite dans un réacteur de polymérisation en phase gazeuse sans obturer la buse d'injection de catalyseur. Combiner le précurseur de catalyseur non supporté au co-catalyseur puis ajouter le solvant supplémentaire pour former la composition selon l'invention empêche l'obturation de la trémie, permet d'obtenir une matière de catalyse à haute activité, empêche la formation de quantités importantes d'agglomérats de polymères et évite l'encrassement du réacteur.
