About company
East West Copolymer's (formerly Lion Copolymer) SBR/NBR site has been a landmark of Baton Rouge, Louisiana, since the 1940s. The facility was designed and built by the U.S. Government during World War II, and since then has played a major role in the development and advancement in synthetic rubber technology. Operations of the SBR facility began in 1943 with a hot emulsion polymerization process. Soon after, in 1948, the facility retooled its operations and developed the first cold polymerization plant in North America. This allowed for better process control and end physical properties of most grades of SBR rubber. With almost two decades passing, the Baton Rouge facility then designed and modified part of its facility to produce NBR grades of rubber, completing this effort in 1965.
