Butyl methacrylate is the organic compound with the formula C₄H₉O₂CC(CH₃)=CH₂. A colorless liquid, it is a common monomer for the preparation of methacrylate polymers.^[1] It is typically polymerized under free-radical conditions.^[2]

Health hazards edit

In terms of the acute toxicity of butyl methacrylate, the LD50 is 20 g/kg (oral, rat). It is an irritant to the eyes and can cause blindness.^[1]
