Taking the average value of k, t 1/2 , E a , ∆S, ∆H, and ∆G, generally, VE_5% MEPECO shows an improvement in thermodynamically kinetic parameters (15.16% increase in activation energy), which Here, we can further assess that the correlation between thermal stability and flammability properties in thermoset resin blends is an important consideration when designing materials for various applications. Understanding the relationship between thermal stability and flammability is crucial for ensuring the safety and performance0 of these materials. In many cases, there is a trade-off between thermal stability and flammability. But in our study, the potential improvement in flammability property while improving the thermal stability of vinyl ester resin is an important result where materials must withstand high temperatures and be fire-resistant, for instance, in developing composites for the aerospace industry. In automotive and electronics, where heat dissipation is important, thermoset resin blends with good thermal stability are used, and flame-retardant properties are also crucial to preventing fires.
