GENERAL HINTS
Can burn in fire! Polymerization may be initiated by contamination with peroxides, azo compounds. Heavy metal ions, tert. Amines, S compounds. Polymerization is also induced by light. Atomospheric oxygen saturation in the monomer is necessary for stability. Storage temperatures should not exceed 35 degree.
