摘要
This invention relates to an activator composition comprising (i) an organoaluminum compounds; (ii) a carbocation compound of the formula R1(X)n; wherein R1 is a hydrocarbyl; n is from 1 to the number of possible substitutions of the hydrocarbyl group and each X is a labile leaving group; and (iii) an aluminoxane. The activator composition may also contain a carrier support. This invention also provides a catalyst composition comprising the activator composition described above and a transition metal component. This invention also provides methods of polymerizing monomer comprising carrying out such polymerization in the presence of one or more catalyst composition according to this invention.
