Synthesis and Application of Arylaminophosphazene as a Flame Retardant and Catalyst for the Polymerization of Benzoxazines

A novel type of phosphazene containing an additive that acts both as a catalyst and flame retardant for benzoxazine binders is presented in this study. The synthesis derivative hexachlorocyclotriphosphazene (HCP) meta-toluidine was carried out the medium latter, which made it possible to achieve complete substitution chlorine atoms initial HCP. Thermal flammability characteristics modified compositions were investigated. modifier catalyzes process curing shifts beginning reaction from 222.0 °C pure 205.9 composition with 10 phr modifier. decreases glass transition temperature compositions. Achievement highest category resistance (V-0 accordance UL-94) ensured by increasing content phenyl residues synergistic effect phosphorus nitrogen. brief study kinetics disclosed complex nature reaction. An accurate two-step model obtained using extended Prout–Tompkins equation steps.
