The process includes preparing a Ziegler-Natta (ZN) catalyst by contacting the ZN catalyst with at least one aluminum alkyl compound to produce a reduced ZN catalyst and storing and/or transporting the reduced ZN catalyst for at least 20 days at a temperature of 25°C or less. The reduced ZN 0 catalyst may be used for polymerizing polyolefin polymers.
