Abstract

Novel methods of promptly detecting polymer sheets formed on the interior wall of gas-phase polymerization reactor have been developed. During reactor operation, polymer particles may attach on the reactor wall due to various reasons. Such an attachment can accumulate and develop to form so called "sheet", meaning a layer of agglomerated or melted or half-melted polymer material.
