Methacrylic acid, abbreviated MAA, is an organic compound. Este líquido incoloro e viscoso é un ácido carboxílico cun cheiro desagradable acrido. É soluble en auga morna e miscible coa maioría dos disolventes orgánicos. 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.
