General hints
Can burn in fire! Polymerization may be initiated by contamination with peroxides, azo compounds, heavy meal ions, tert. Amines, s compounds. Polymeriztion is also induced by light. Atomospheric oxygen saturation in the monomer is necessary for stability. Storage temperatures should not exceed 35 degree.
