ABSTRACT Alpha-olefins are polymerized in the presence of at least two independently supported catalysts, one an inorganic halide supported titanium and/or vanadium Ziegler type catalyst and another an inorganic oxide supported, chromium catalyst. This dual catalyst blend increases catalyst efficiency and/or provides more flexible control of the properties of the resulting polymers. 28,099A-F
