ABSTRACT OF THE DISCLOSURE The copolymerization of ethylene with other alpha olefins in a low pressure gas phase reaction is improved with the use of a catalyst composition prepared by forming a precursor composition from a magnesium com- pound, titanium compound and electron donor compound; diluting said precursor composition with an inert carrier material; treating said diluted precursor composition with a hydrocarbyl aluminum dihalide compound; and activating the precursor composition treated in this manner with an organo aluminum compound.
