Description
Structurally, it contains both a carboxylic acid group and an α,β-unsaturated double bond (CH₂=C(CH₃)COOH). At room temperature, it exists as a colorless liquid or low-melting solid (m.p. 15°C) with a strong acidic odor. It readily undergoes polymerization and is typically stored with inhibitors.

Separated from strong oxidants and food and feedstuffs. Cool. Keep in the dark. Keep in a well-ventilated room. Store only if stabilized.
May be stabilized by the addition of MEHQ (Hydroquinone methyl ether, ca. 250 ppm) or hydroquinone. In the absence of a stabilizer this material will readily polymerize. Combustible. Incompatible with strong oxidizing agents, hydrochloric acid.

Methacrylic acid Use and Manufacturing
Methacrylic acid, abbreviated MAA, is an organic compound. This colorless, 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 Plexigl
