More Information
Summary:A polymerization process is disclosed, including: polymerizing an olefin to form an olefin-based polymer in a polymerization reactor; and introducing a hindered amine light stabilizer 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 hindered amine light stabilizer, the hindered amine light stabilizer 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.
