ABSTRACT:
Olefins are polymerized with a catalyst system composition comprising a nickel compound and an aromatic carboxylic acid wherein there is a heteroatom linkage between the aromatic moiety and the carboxylic acid functional group. The novel catalyst system composition can be heterogeneous or homogeneous. This composition allows the production of one or more olefin polymers which have a very high molecular weight.
