Physical description & handling notes

• Liquid
• log Kow = 7.66 /Estimated/
• Henry's Law constant: 2.5X10-2 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/
• Index of refraction: 1.4480 @ 20 °C/D
• Hydroxyl radical reaction rate constant: 3.7X10-11 cu cm/molecule-sec @ 25 °C /Estimated/
