PITTSBURGH (July 24)—Bayer Corp. plans to close its polyurethane-focused research and development location in Newtown Square, Pa., by the end of 2002. The unit was acquired late in 1999 when Bayer A.G., the U.S. firm's parent, took over Lyondell Chemical Co.'s polyols business. About half of the 110 Bayer employees in Newtown Square are expected to relocate to other Bayer polyurethane centers in Pittsburgh or South Charleston, W.Va., according to the company. Bayer also is closing a plastics R&D site in Springfield, Mass., and moving 100 engineers to Baytown, Texas, from Pittsburgh. The engineer transfer will be completed by the end of 2003 and will reduce Bayer's overhead and travel costs, since many staff members frequently travel between Pittsburgh and Baytown to consult on plant operations and other projects. Bayer could not specify the level of annual savings that would result from either the Pittsburgh-Baytown move or the Newtown Square and Springfield closures.
