Applications:

• Polymer Production: Used to produce poly(methyl methacrylate) (PMMA), also known as acrylic glass or plexiglass.

• Coatings: Used in the production of paints, coatings, and varnishes.

• Adhesives: Used in adhesive formulations.

• Medical and Dental: Used in the production of prosthetic devices, surgical bone cements, and dental materials.

• Automotive: Used in the production of automotive parts and coatings.

Methyl Methacrylate is produced by the acid-catalyzed esterification of methacrylic acid with methanol. It polymerizes easily, so commercial preparations often contain polymerization inhibitors such as hydroquinone2.

Other Names:

• Methyl-2-methylpropenoate

• Methyl methacrylate (stabilized with hydroquinone)

• MMA

• 80-62-6 (CAS number)
