Poly(methyl methacrylate) (PMMA) is the synthetic polymer derived from methyl methacrylate. Being an engineering plastic, it is a transparent thermoplastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Alfaplas, Plexiglas, Acrylite, Astariglas, Lucite, Perclax, and … See more It was developed in 1928 in several different laboratories by many chemists, such as William R. Conn, Otto Röhm, and Walter Bauer, and first brought to market in 1933 by German Röhm & Haas AG (as of January 2024, … See more PMMA can be joined using cyanoacrylate cement (commonly known as superglue), with heat (welding), or by using chlorinated solvents such as See more PMMA is a strong, tough, and lightweight material. It has a density of 1.17–1.20 g/cm , which is less than half that of glass. It also has good … See more The polymer of methyl acrylate, PMA or poly(methyl acrylate), is similar to poly(methyl methacrylate), except for the lack of methyl groups on the backbone carbon chain. PMA … See more PMMA is routinely produced by emulsion polymerization, solution polymerization, and bulk polymerization.
