Used as a reactive monomer in the synthesis of high-performance polymers due to its dual allyl groups and phenolic hydroxyl functionality. Enables crosslinking in thermosetting resins, improving thermal and oxidative stability. Applied in specialty coatings, adhesives, and composite materials where enhanced durability and resistance to high temperatures are required. Also serves as an intermediate in the production of flame-retardant additives and UV-resistant polymers. Its structure supports radical polymerization and can be incorporated into epoxy and unsaturated polyester systems for advanced material applications.
