BRIEF OVERVIEW
Methyl Methacrylate is a methyl ester of methacrylic acid. Methyl methacrylate is a reactive resin, and the polymerized form is used as cement in dentistry, orthopaedic surgery and ophthalmology. The monomer form of this agent has relaxation effect on smooth muscle systemically, which might be a result of nitric oxide-mediated response.
MANUFACTURING PROCESS
Acetone and hydrogen cyanide are first reacted to produce acetone cyanohydrin. Sulphuric acid converts the cyanohydrin to methacrylamide sulphate which is then treated with a methanol/water mixture and heated to form MMA and ammonium bisulphate.
MEDICINE
Methyl methacrylate (C5H8O2) is used in the manufacture of resins and plastics, and as an enteric coating for tablet medications. Enteric coatings prevent stomach dissolution. Medicines that have an irritant effect on the stomach, such as aspirin or ibuprofen, can be enteric coated and will only dissolve in the small intestine.
MODIFIER PVC
Methyl methacrylate is also used for the production of the co-polymer methyl methacrylate-butadiene-styrene (MABS), used as a modifier for PVC.
