Bayer MaterialScience is an independent subgroup within Bayer AG. It was created as part of the restructuring of Bayer AG from the former business group Bayer Polymers, with certain of its activities being spun off to Lanxess AG. BMS manufactures and develops materials such as coatings, adhesives and sealants, polycarbonates , polyurethanes etc.The main industries served are automotive manufacturing and supply, electrical engineering and electronics, construction and home products, and sports and leisure.Bayer MaterialScience has approximately 30 production sites around the globe.The company is divided into 3 principal Business Units that comprises the core segment of BMS. These are: BU Coatings, Adhesives, Specialties BU Polycarbonates BU Polyurethanes On September 18, 2014, the Board of Directors of Bayer AG announced plans to float the Bayer MaterialScience business on the stock market as a separate entity.

A process for endowing a polymeric article with a surface layer of an ion-conducting polymer to yield electrical surface resistivity sufficiently low for electrostatic discharge applications is provided. The polymeric article contains one or more immobilized, polymeric components having amine functional groups. The presence of the ion-conducting polymer in the surface layer lowers the surface electrical resistivity into the range suitable for electrostatic discharge applications, between about 110
