ABSTRACT:
The present invention relates to an olefin polymerization catalyst obtainable by depositing on a dry inorganic oxide support a monocuclear chromium complex to produce a catalyst precursor and thereafter by thermally activating the said catalyst precursor. The catalyst is characterized in that the mononuclear chromium complex is representable by the general formula: ##STR1## wherein: the cyclopentadienyl ligand is substituted with 4 or 5 hydrocarbon groups containing 1 to 3 carbon atoms,
