ABSTRACT:
Catalyst compositions suitable for producing high density ethylene polymers in a low pressure gas phase process with low accompanying ethylene hydrogenation are produced by forming a precursor composition from a magnesium compound, titanium compound and electron donor compound; diluting said precursor composition with an inert carrier material; treating said diluted precursor composition with a boron halide compound; and activating the precursor composition with an organo aluminum compound.
