Organic compound with the formula CH₂=CCOOCH₃, CAS 80–62–6 Used in n chain-addition polymerizations, in the manufacture of methacrylate resins and plastics (e.g., Plexiglas; advertising signs and displays, lighting, plumbing and bathroom fixtures; lacquer, and enamel resins; concrete additives, and prosthetic medical devices - such as hip and knee joint prostheses). It can be detected in small concentrations in human breath - Streptococcus pneumonia infections, for example, increase its concentrations up to 1420 ppb.
Methyl methacrylate is a flammable and reactive chemical, fire and explosion hazard. Breathing it in can irritate the lungs causing coughing and or shortness of breath. Higher exposures can cause a build up of fluid in the lungs and pulmonary edema. It can affect liver and kidneys, damage nervous system, causing numbness, “puns and needles”, and/or weakness in the hands and feet, and may cause a skin allergy. High exposure can cause dizziness, irritability, difficulty with concentration and reduced memory. Workplace exposure limits are 100 ppm over 8 hrs shifts or 50 ppm if longer term exposures.
