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