CA 2369101

An olefin polymerization process is described. The process comprises polymerizing an olefin in the presence of a supported single-site catalyst, an optional activator, and a fatty amine. The fatty amine is added at a concentration in the range from about 10 to about 75 weight percent based on the weight of the supported catalyst. The fatty amine helps to reduce fouling and sheeting during the polymerization process and enhances catalyst activity.

L'invention se rapporte à un procédé de polymérisation d'oléfines. Ledit procédé consiste à polymériser une oléfine en présence d'un catalyseur supporté et monosite, d'un activateur optique et d'une amine grasse. La concentration de cette amine grasse utilisée comme additif est comprise entre 10 % en poids environ et 75 % en poids environ, par rapport au poids du catalyseur supporté. Cette amine grasse permet de réduire l'encrassement et l'exfoliation pendant le processus de polymérisation et elle accroît l'activité catalytique.
