What is Methyl Methacrylate
Analysts Sentiment
What's driving sentiment this week:
Methyl methacrylate (MMA) is a colorless, volatile liquid organic compound with the molecular formula C5H8O2 and CAS number 80-62-6. It is the methyl ester of methacrylic acid and belongs to the family of acrylic monomers. MMA is primarily used as a monomer to produce poly(methyl methacrylate) (PMMA), a transparent thermoplastic widely known under trade names such as Plexiglas, Lucite, and Perspex. It is also a key comonomer in acrylic emulsions, surface coatings, adhesives, and specialty polymers. MMA is a reactive monomer that polymerizes readily under heat, light, or free-radical initiators, and it is handled with inhibitors (typically hydroquinone monomethyl ether) to prevent premature polymerization during storage and transport. It has a boiling point of approximately 100.5°C, a density of about 0.94 g/cm³, and is slightly soluble in water but miscible with most organic solvents.
