Patent ID: 8088870

Claim:
A method of producing a polymer product in a fluidized bed polymerization reactor system, including the steps of: (a) treating at least one interior surface of the reactor system using a solution catalyst comprising at least one catalyst dissolved in at least one solvent, including by applying the solution catalyst at least substantially uniformly and in liquid form to each said surface, wherein contents of the reactor during step (a) have a dew point temperature, and said contents include the solution catalyst, while maintaining conditions in the reactor system, including reactor temperature, sufficient to maintain the dew point temperature at the reactor temperature during uniform wetting of each said interior surface by the solution catalyst; and (b) performing a first polymerization reaction, catalyzed by the catalyst, to form on each said surface a polymer coating; and (c) after step (b) performing a second polymerization reaction in the reactor system to produce the polymer product, wherein the second polymerization reaction is catalyzed by one of a second catalyst and a second catalyst system, and the polymer coating formed in step (b) produces an insulating layer to reduce static charging in the reactor system during performance of the second polymerization reaction.
