Used primarily as a reactive monomer in polymer synthesis, enabling the production of specialty resins with enhanced adhesion and flexibility. Commonly employed in pressure-sensitive adhesives, coatings, and sealants due to its ability to copolymerize with other vinyl monomers. Its aromatic and vinyl functionalities contribute to improved thermal stability and crosslinking density in final polymer products. Also utilized in the development of functional polymers for printing inks and textile treatments where water resistance and durability are required.
