Abstract
Catalyst compositions that include a vanadium compound can be used to polymerize ethylenically unsaturated hydrocarbon monomers that include at least one polyene and at least one C?2#191-C?8#191 α-olefin, with the presence of a highly halogenated ketone increasing the activity of the catalyst composition while not negatively impacting the relative percentage (molar) of olefin mer incorporation.
