ABSTRACT:
A method for preparing an activated catalyst composition comprising a single site catalyst precursor and an activating cocatalyst, which comprises contacting outside of a polymerization reactor a single site catalyst precursor with an activating cocatalyst before, during, or after contacting the single site catalyst precursor with a weakly coordinating electron donor such as 1-hexene.
