Catalyst activation in a dual reactor process

摘要

Catalysts are activated in a dual reactor solution process by adding substoichiometric and superstoichiometric amounts of an ionic activator to an organometallic polymerization catalyst in a first and second reactor respectively. The new activation method allows one to alter process conditions in a favorably way with minimum impact to process economics. The new activation method also provides polymers which give films having improved optical properties.
