In 1843, chemist John Edward Simon first discovered and described an unknown acidic substance, namely methacrylic acid, in the fractionation product of a substance called "pyroxylic acid" (wood vinegar) in Germany. He named this acid "one of the pyrolignans" at the time, but was unable to fully determine its structure, let alone synthesize its esters.
Decades later, in 1865, chemists William Henry Parkin and others independently synthesized this acid again through a new method and correctly determined its chemical structure. They named it 'Methacrylic Acid', meaning 'Methacrylic acid', which has been used to this day. After clarifying the structure of acids, chemists began synthesizing their various esters.
Around 1880, German chemists Moritz Freiherr von Losko and Otto Sharbach first synthesized methyl methacrylate monomer through the esterification reaction of methyl methacrylate with methanol.
In 1901, German chemist Otto Roem began systematic research on acrylic acid and methacrylate esters. He found that these esters turn into hard, transparent glassy substances when heated, illuminated, or exposed to air.
In 1933, Rohm&Haas successfully achieved industrial production of polymethyl methacrylate and commercialized it, registering the trademark "Plexiglas" (Persper Organic Glass). Almost at the same time, DuPont in the United States also independently developed a similar product called "Lucite".
