Application

Triallyl phosphate serves as a versatile crosslinking agent in polymer chemistry, particularly for enhancing thermal stability in allyl-functionalized resins. Its three reactive allyl groups make it valuable for creating flame-retardant materials through copolymerization with vinyl monomers. Researchers employ this compound as a reactive diluent in specialty adhesives and as a precursor for phosphorus-containing dendrimers. In material science, it functions as a plasticizer modifier for improving the flexibility of phosphate-based polymers while maintaining flame resistance.
