99% Methacrylic acid MAA CAS 79-41-4

Methacrylic acid Basic information

     Methacrylic acid, abbreviated MAA, is an organic compound.  This colourless, viscous liquid is a carboxylic acid with an acrid unpleasant odor.  It is soluble in warm water and miscible with most organic solvents.  Methacrylic acid is produced industrially on a large scale as a precursor to its esters, especially methyl methacrylate (MMA) and poly(methyl methacrylate) (PMMA).  The methacrylates have numerous uses, most notably in the manufacture of polymers with trade names such as Lucite and Plexiglas.  

     MAA occurs naturally in small amounts in the oil of Roman chamomile.

    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.
