methylmetakrylátu

Methyl methacrylate, often abbreviated as MMA, is an organic compound with the formula CH2=C(CH3)COOCH3. It is a colorless, volatile liquid with a distinct acrid odor. MMA is a monomer, meaning it is a small molecule that can link together with other identical molecules to form a polymer. The polymerization of methyl methacrylate results in poly(methyl methacrylate), commonly known as PMMA or acrylic glass.

PMMA is a transparent thermoplastic that is more resistant to breakage than ordinary glass. It is widely used in various applications, including shatterproof windows, signage, aquariums, and lenses. MMA is also a key component in many dental applications, such as dentures and fillings, as well as in bone cement used in orthopedic surgery.

Industrially, methyl methacrylate is primarily produced through the acetone cyanohydrin process. Other methods include the C4 oxidation process. MMA is a reactive chemical and must be handled with care due to its flammability and potential health effects. Inhalation of high concentrations of MMA vapor can cause respiratory irritation and other health issues. It is also a skin irritant.

The production and use of methyl methacrylate are significant in the chemical industry, contributing to the manufacturing of a wide range of products that benefit various sectors of society. Its versatility and the desirable properties of its polymerized form make it an important industrial chemical.
