Used primarily as an antioxidant and stabilizer in polymers and plastics to prevent degradation caused by oxidation. It helps extend the lifespan of materials like rubber, adhesives, and coatings by inhibiting the formation of free radicals. Additionally, it is employed in the production of synthetic resins and as an additive in lubricants to enhance thermal stability. Its vinyl group allows it to participate in polymerization processes, making it useful in creating specialized polymers with improved durability and resistance to environmental factors.
