Description and Uses
Methacrylic anhydride is a reactive monomer used primarily as a monomer in the preparation of polymers, particularly poly(methacrylic acid) and its copolymers. The reaction mechanism involves the formation of covalent bonds between methacrylic acid and acetic anhydride molecules, resulting in the formation of a novel compound. The newly formed compound then undergoes a series of reactions including hydrolysis and polymerisation. Methacrylic anhydride produces polymers with good chemical and thermal stability, which are used in a wide range of applications in various industries such as bio-renewable resins, pH-sensitive hydrogels, thermoset plastics, coatings, adhesives and plastics.
Methacrylic anhydride is a reactive monomer used for the preparation of different type of monomers under mild reaction conditions. It finds applications in light-curing coatings, cross-linked materials like synthetic resin. It acts as an intermediate for the preparation of fibers and resins.
