3. Chemical Properties and Stability
- Stability: Stable under recommended storage conditions. Typically supplied with a polymerization inhibitor (e.g., MEHQ).
- Incompatibilities: Incompatible with strong oxidizing agents, strong bases, strong acids, reducing agents, peroxides, and free-radical initiators.
- Hazardous Polymerization: May occur if not properly inhibited or if exposed to high temperatures, direct sunlight, UV radiation, or contaminants. Polymerization is a highly exothermic reaction and can be rapid and violent.
- Hazardous Decomposition Products: Combustion may produce toxic fumes of carbon monoxide (CO) and carbon dioxide (CO2?).
