An aluminum activator and catalyst system for olefin polymerization is provided. In one aspect, the catalyst system comprises a polymerization catalyst and an activator comprising two or more heterocyclic nitrogen- containing ligands coordinated to a Group 13 atom. Preferably, the activator is a reaction product of one or more Group 13 atom-containing compounds and one or more heterocyclic nitrogen-containing compounds.

L'invention concerne un activateur d'aluminium et un système catalytique permettant la polymérisation des oléfines. Dans un aspect de cette invention, le système catalytique comprend un catalyseur de polymérisation et un activateur contenant au moins deux ligands hétérocycliques à teneur en azote qui sont coordonnés à un atome du groupe 13. De préférence, l'activateur est un produit de réaction d'un ou de plusieurs composés contenant un atome du groupe 13 avec un ou plusieurs composés hétérocycliques contenant un atome du groupe 13.
