ABSTRACT:
Olefin polymerization catalysts are described which are based on solid inorganic oxides (such as silica) and polychromium complexes (such as octakis(.mu.-trimethylsilylmethyl)tetrachromium(II)). Linear low density ethylene homopolymers with specific short chain branching as well as polymerization processes to make these polymers using the specific catalyst described are also disclosed.
