Abstract
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.
