ABSTRACT:
Olefins can be polymerized in the presence of a catalyst system composition comprising chromium supported on an inorganic oxide support, a pyrrole-containing compounds, and a metal alkyl. The use of this type of polymerization process can produce an olefin comonomer in-situ, resulting in polymers having decreased density and increased branching.
