1. As a vinyl monomer, it is used as an efficient polymerization inhibitor for conjugated olefins.
2. It can be used as a high-efficiency terminal polymerization inhibitor in the presence of terminal polymerization seeds in the liquid or gas phase.
3. It is an excellent terminator for the styrene-butadiene emulsion polymerization process.
4. It is an antioxidant for unsaturated oils and resins.
5. It is a good stabilizer for photosensitive resin, photosensitive emulsion and synthetic resin.
6. It is a good photochemical smog inhibitor in environmental protection.
7. It is a corrosion inhibitor for boiler feed water and steam heat exchange equipment.
