Physical description & handling notes

• Liquid
• Clear colorless liquid with a pungent odor; [ACGIH]
• Colorless liquid.
• Colorless liquid
• When heated to decomposition it emits acrid smoke and irritating fumes.
• Methyl methacrylate, and in general the methacrylic esters, polymerize much less readily than the corresponding ordinary acrylates. None the less, they are stabilized by adding hydroquinone or pyrogallol, particularly in the presence of metallic copper. /Methacrylates/

Documented Uses

• Used as a monomer, intermediate, and cross-linking agent (contact lenses); Also used in acrylic coatings; [HSDB] Used mainly in closed system processing as a co-monomer (rigid plastics) and cross linker (silanes); Also used in coatings, photoresists, adhesives, dental composites, floor polishes, and vulcanized rubber; [ACGIH]
• Painting (Pigments, Binders, and Biocides) [Category: Paint]
• Plastic Composites Manufacturing [Category: Industry]
• Cross-linking agent with methacrylate esters in contact lenses and with alkyl acrylates in pressure-sensitive adhesives; in curable acrylic coatings; for preparing mucilages and thickening agents for aqueous systems
• Not Known or Reasonably Ascertainable
• Alcoholysis of methyl methacrylate by allyl alcohol in the presence of sodium methylate and hydroquinone, a polymerization inhibitor; also can be made by esterification of the acid by allyl alcohol. Hydroquinone can be removed by distillation or washing with 5% sodium hydroxide.
