Title: BRANCHED PROPYLENE POLYMERS PRODUCED VIA USE OF VINYL TRANSFER AGENTS AND PROCESSES FOR PRODUCTION THEREOF
Abstract:
This invention relates to the use of pyridyldiamido and/or quinolinyldiamido transition metal complexes and catalyst systems with an activator and a metal hydrocarbenyl chain transfer agent, such as an aluminum vinyl-transfer agent (A VTA), to produce branched propylene polymers, preferably propylene-ethylene copolymers or propylene-ethylene-diene monomer copolymers.
