Descripción general

Methacrylic acid (MAA) is an organic compound, colorless, viscous liquid. It is a monofunctional methacrylayte monomer.[1] It is soluble in warm water and miscible in most organic solvents. MAA is used as a starting material for the production of its esters, especially methyl methacrylate and poly methyl methacrylate (PMMA).[2]

Aplicación

MAA is used to synthesize poly(methacrylic acid)-g-poly(ε-caprolactone) copolymers,[3] polymeric blends with PMMA[4] and hydroxyethyl methacrylate (HEMA)-MAA hydrogels.
