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 (AVTA), to produce branched ethylene copolymers, preferably ethylene-butene, ethylene-hexene and ethylene-octene copolymers.
