ABSTRACT The invention provides a process for pre-polymerizing olefin polymerization catalysts and a process for increasing the efficiency of pre-polymerized olefin polymerization catalysts. In one process of this invention an olefin monomer is added to a fluid carrier stream containing an olefin polymerization catalyst. The carrier stream containing the monomer and the catalyst is passed through an elongated tubular reactor at a flow rate sufficient to provide a residence time in the tubular reactor of less than 1 minute and under temperature conditions to pre-polymerize the catalyst within the tubular reactor without plugging of the reactor. In another process of this invention a pre-polymerized catalyst is contacted with a cocatalyst or a mixture of cocatalyst and an electron donor prior to introducing the catalyst into a polymerization reaction zone.
