Used primarily as a reactive monomer in polymer synthesis, this compound enhances the thermal and mechanical properties of resins. Its aromatic structure contributes to increased glass transition temperature (Tg) in polymers, making it valuable in high-performance coatings and adhesives. It is also employed in specialty plastics requiring improved rigidity and chemical resistance. Due to its ability to copolymerize with other vinyl monomers, it finds use in emulsion polymers for industrial applications where durability and stability are critical. Additionally, it serves in the development of photoresists and optical materials owing to its UV absorption characteristics.
