Polymethyl methacrylate was found out inside the early 1930s by British chemists Rowland Hill and John Crawford at Imperial Chemical Industries (ICI) in England. ICI registered the item beneath the trademark Perspex. Regarding the similar time, chemist and industrialist Otto Röhm of Rohm and Haas AG in Germany attempted to produce basic safety glass by polymerizing methyl methacrylate in between two layers of glass. The polymer divided in the glass as a clear plastic sheet, which Röhm gave the trademarked identify Plexiglas in 1933.
