Ternary flame-retardant modified cyanate ester blends (CEPG and CEPA) are formed by combining triazine compounds (TGIC or TAIC) and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide with cyanate ester resin. The curing behaviors, thermal and mechanical properties, and the flame-retardant properties are investigated. The results show that the CEPG and CEPA blends result in lower curing temperatures and glass transition temperatures than those of neat CE. Both of CEPG and CEPA blends significantly improve the flame-retardant properties of CE resins, and UL-94V-0 rate is achieved for CEPG-1.0 an...
