    摘要: A polymerization process is disclosed comprising polymerizing an olefin to form an olefin-based polymer in a polymerization reactor; and introducing a polyetheramine additive to the polymerization reactor. The process may further comprise monitoring static in the polymerization reactor; maintaining the static at a desired level by use of a polyetheramine additive, where the polyetheramine additive is present in the reactor in the range from about 0.1 to about 500 ppmw, based on the weight of polymer produced by the process.
