Abstract:
The invention relates to a process for the polymerization of olifins in the presence of 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 that does not substantially polymerize during either contacting.
