摘要：
A method for making a support impregnated Ziegler-Natta-type catalyst precursor including at least two transition metals and a support material wherein the resulting catalyst precursor is free-flowing is provided. Also provided is a process for producing a Ziegler-Natta type procatalyst by halogenating the free flowing catalyst precursor. The Ziegler-Natta type procatalyst and the reaction product of at least one monomer in the presence of the Ziegler-Natta type procatalyst and cocatalyst are also provided.
