Physical description & handling notes

• Liquid
• Clear odorless liquid; [MSDSonline]
• 1.02X10-4 mm Hg @ 25 °C (Extrapolated)
• log Kow = 8.64 /Estimated/
• Henry's Law constant: 5.0X10-2 atm-cu m/mol @ 25 °C /Estimated/
• 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 monomer (i.e. for motor oil viscosity index improvers and its homopolymer); [HSDB]
• COMONOMER, EG, FOR MOTOR OIL VISCOSITY INDEX IMPROVERS.
• The methacrylates can be synthesized by catalytic oxidation of isobutylene and subsequent esterification with the appropriate alcohol, or by reacting acetone with hydrocyanic acid and subsequent esterification in sulfuric acid with the appropriate alcohol. /Methacrylic esters/
