Abstract
A stable, long-lived catalyst composition, well suited for the polymerization of olefins, e.g., of ethylene, comprises intimate admixture of particulates of an olefin prepolymer and a catalytically effective amount of particles of a metallic olefin polymerization catalyst, such olefin prepolymer particulates having a particle size distribution narrower than the particle size distribution of the metallic catalyst particles.
