Use
Methacrylic acid is used in the manufacture of methacrylate resins and plastics. It is used as Monomer for large-volume resins and polymers, organic synthesis. Many of the polymers are based on esters of the acid, as the methyl, butyl, or isobutyl esters. Methacrylic acid and methacrylate esters are used to prepare a wide range of polymers [→ Polyacrylamides and Poly(Acrylic Acids), → Polymethacrylates]. Poly(methyl methacrylate) is the primary polymer in this category, and it provides water-clear, tough plastics that are used in sheet form in glazing, signs, displays, and lighting panels.
