ABSTRACT:
A method for passivating internal surfaces of a reactor system during start-up and shutdown of an alpha olefin polymerization or copolymerization reaction by adding a passivation agent such as a dialkyl zinc compound, an alcohol, or an epoxide, to the reactor prior to exposing the internal reactor surfaces to air or moisture before reaction initiation and/or after reaction ceases.
