- olefin polymers and copolymers such as ethylene polymers, propylene polymers and ethylene-alphaolefin copolymers have been prepared by heterogeneous catalysts consisting of titanium compounds and alkylaluminum compounds.

- Early single site homogeneous catalysts were in the form of metallocene compounds of Group 4 metals coordinated by two cyclopentadienyl ligands activated by methylaluminoxane (MAO).
