    Abstract: An olefin polymerization process is described. The process comprises polymerizing an olefin in the presence of a support, a single-site catalyst, an optional activator, and a fatty amine. The support is chemically treated with an organoboron compound. The single-site catalyst contains a polymerization-stable, heteroatomic ligand. The fatty amine is added directly to the reactor. The combination of pre-treating the support with an organoboron compound and the addition of fatty amine to the process unexpectedly increases catalyst activity.
