Used primarily as a reactive monomer in polymer synthesis, enabling the incorporation of sulfur-containing moieties into copolymers for enhanced flexibility and adhesion. Employed in specialty coatings and adhesives where improved substrate bonding is required. Acts as a crosslinking agent in UV-curable systems, contributing to faster curing and increased chemical resistance. Also utilized in the development of functional polymers for optical and electronic applications due to its unique electronic properties from the phenylthio group.
