Description and Uses

Methyl methacrylate is an organic compound with the formula CH2=C(CH3)COOCH3. This colourless liquid, the methyl ester of methacrylic acid (MAA) is a monomer produced on a large scale for the production of poly(methyl methacrylate) (PMMA).

Methyl methacrylatec is used in acrylic bone cements used in orthopedic surgery; in the production of acrylic polymers, polymethylmethacrylate and copolymers used in acrylic surface coatings; in the manufaeture of emulsion polymers; in the modification of unsaturated polyester resins; in the production of higher methacrylate, acrylic fibers, acrylic film, inks, radiation-polymerized impregnants for wood, and solvent-based adhesives and binders; as an impact modifier of PVC; in medicinal spray adhesives; in nonirritant bandage solvents; in dental technology as ceramic filler or cement; to coat corneal contact lenses; in intraocular lenses, artificial nails, and hearing aids; as a monomer for polymethaerylate resins; in the impregnation of concretc.

Toxicity The acute toxicity of methyl methacrylate is low. Irritation of the skin, eye, and nasal cavity has been observed in rodents and rabbits exposed to relatively high concentrations of methyl methacrylate. The chemical is a mild skin sensitizer in animals. The effect observed most frequently at lowest concentration after repeated inhalation exposure to methyl methacrylate is irritation of the nasal cavity. Effects on the kidney and liver at higher concentrations have also been reported.
