This invention relates to a process to produce an ionomer comprising: 1) contacting, in a reactor, one or more C-Cα-olefins, an optional diene, and a metal alkenyl with a catalyst system comprising an activator, a catalyst compound, and a support; 2) forming a copolymer comprising one or more C-Cα-olefin monomers and about 0.01 wt % to about 20 wt %, based on the weight of the copolymer, of metal alkenyl; 3) functionalizing and quenching the polymerization reaction with one or more electrophilic groups; and 4) obtaining ionomer.

Polyolefin-based ionomers and production thereof

The present disclosure provides pyridyl hydroxyl amine catalyst compounds and systems containing the compounds. The present disclosure is also directed to polymerization processes to produce polyolefin polymers from catalyst systems including one or more olefin polymerization catalysts, at least one activator, and an optional support. The compounds are represented by Formula I(a), I(b) or I(c):
