N2 - Vinyl ester resin (VER) and its glass fiber composites are widely utilized in various industries due to the excellent overall properties. However, flame retardancy remains a key factor limiting the broader application of VER. In this study, we synthesized a new intrinsically flame-retardant vinyl ester resin monomer OPBMA-DOPO, through the reaction of Schiff base and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO), and compared its properties with the commercial VER resin. The cured sample (OPBMAR-DOPO) and its glass fiber composite (OPBMAR-DOPO/GF) exhibit excellent flame retardant properties. Compared to VER, OPBMAR-DOPO exhibits a 51.18 % reduction in total heat release (THR) and a 40.55 % decrease in total smoke production (TSP). When compared to VER/GF, OPBMAR-DOPO/GF shows a 9.76 % decrease in THR and a 28.7 % reduction in TSP. The limited oxygen index (LOI) of OPBMAR-DOPO is 29.2 %, and for OPBMAR-DOPO/GF is 48.2 %, which are significantly higher than that of VER and VER/GF. Additionally, the mechanical properties of OPBMAR-DOPO and its glass fiber composite are superior to VER. Furthermore, the flame retardant mechanism of OPBMAR-DOPO was investigated. This study contributes to expanding the application areas of vinyl ester resin.
