Although it is not technically a type of glass, the substance has sometimes historically been called acrylic glass. Chemically, it is the synthetic polymer of methyl methacrylate. The material was developed in 1928 in several different laboratories by many chemists such as William Chalmers, Otto Röhm and Walter Bauer and was first brought to market in 1933 by the Rohm and Haas Company, under the trademark Plexiglas.[4] It has since been sold under many different names, including Acrylite, Lucite, and Perspex.
