Used in the synthesis of specialty polymers and resins due to its reactive vinyl group and aromatic structure. It serves as a monomer in copolymerization processes to produce materials with enhanced thermal stability and mechanical strength. Commonly applied in adhesives, coatings, and sealants where improved chemical resistance is required. Also utilized in the development of functionalized polystyrene derivatives for research and industrial applications. Its methyl group allows for further chemical modification, making it valuable in organic synthesis and polymer chemistry.
