The effectiveness of phenolic inhibitors, eg, monomethyl ether of hydroquinone & hydroquinone, depends on the presence of oxygen. Monomers inhibited with these materials must be stored in air rather than in an inert atmosphere. Contamination must be avoided; eg, moisture may cause rust-initiated polymerization. Temperatures during storage must be kept low to minimize formation of peroxides & other oxidation products. ... In general, the methacrylate monomers should not be stored for longer than
