Metylemetakrylaatti
Metylemetakrylaatti, often abbreviated as MMA, is an organic compound with the formula CH2=C(CH3)COOCH3. It is a volatile, colorless liquid with a characteristic acrid odor. MMA is a monomer, meaning it is a small molecule that can bond to other similar molecules to form a larger polymer. The primary use of methyl methacrylate is in the production of polymethyl methacrylate (PMMA), a transparent thermoplastic commonly known as acrylic glass or Plexiglas.
PMMA possesses several desirable properties, including high transparency, excellent weather resistance, and good impact strength, though
