Methacrylic acid, abbreviated MAA, is an organic compound with the formula CH 2 =C(CH 3)CO 2 H. 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.

Recent progress has been made for (partially) ionized MAA by introducing a new rate law for propagation where electrostatic and non-electrostatic effects are explicitly considered. [7] In addition, the rate constant of propagation (kp) during free radical polymerization of methacrylic acid is dependent on the monomer concentration.
The conversion uses N 2 O 4 and nitric acid at 5–10 °C in the liquid phase. After esterification and dehydration MMA is obtained. Challenges with this route, aside from yield, involve the handling of large amounts of nitric acid and NO x. This method was discontinued in 1965 after an explosion at an operation plant. [10]

Comonomers such as methacrylic acid can be added to increase the glass transition temperature of the polymer for higher temperature use such as in lighting applications. Plasticizers may be added to improve processing properties, lower the glass transition temperature, improve impact properties, and improve mechanical properties such as elastic ...

Methacrylic anhydride is a liquid which reacts with water exothermically. [1] It can also react with hydroxyl and amino groups present in some organic compounds leading to covalent attachment of methacryloyl moieties. These functional groups could be successfully used either in subsequent polymerisation or reactions with thiols.
