DESCRIPTION & APPLICATIONS |
||
|
Methyl methacrylate(MMA) is a flammable, colorless liquid; melting at -48 C, boiling at 101 C, soluble in the most organic solvents but insoluble in water. It is prepared by the esterification of methacrylamide sulfate with methanol. (The reaction of acetone and hydrogen cyanide forms acetone cyanohydrin, which is further treated with sulfuric acid to produce methacrylamide sulfate). Ammonium bisulfate is a byproduct. MMA is the monomer to make polymethyl methacrylate (PMMA) used as a shatterproof replacement for glass. It is is a key ingredient in the production of cast and extruded acrylic sheet, acrylic emulsions, molding powders and extrusion resins. Polymers and copolymers of methyl methacrylate are also used in undissolved surface coatings, adhesives, sealants, impact modifiers, emulsion polymers, surgical bone cements, packaging applications, vinyl siding and other construction materials. |
