Abstract: Disclosed herein is a method for reducing isomerization during the copolymerization of ethylene with an ?-olefin comprising adding to a reactor a reaction mixture comprising hydrogen, ethylene, an ?-olefin, a solvent and a catalyst; where the catalyst does not include a chain shuttling agent that comprises dialkyl zinc; heating the reactor to a first temperature to react the ethylene with the ?-olefin to form a copolymer; discharging from the reactor a first product stream to a heat exchanger; where the product stream comprises the copolymer; adding to the product stream prior to the heat exchanger a first additive that is operative to reduce isomerization of the ?-olefin; and discharging from the heat exchanger a second product stream.
