Halogen-based fire retardants are often used to reduce flammability and improve the fire resistance properties of polymers and fiber-reinforced polymer composites (FRPs). Brominated vinyl ester resins (Br-VERs) are a class of halogenated polymer matrices that are economically viable, high performance materials that are widely utilized in composites for specialty applications, such as the fabrication of hulls in naval vessels. In this work, Br-VE polymer is synthesized from tetrabromobisphenol A (TBBPA) and glycidyl methacrylate (GMA) precursors, and which can be derived from the wastes of the biodiesel and wood pulp industries, respectively. The Br-VE reaction products are analyzed by ¹H NMR and the presence of unreacted (nonfunctional), monofunctional and difunctional TBBPA are confirmed. A baseline formulation of difunctional Br-VE and styrene (40 wt %) is mixed with a commercial brominated vinyl ester resin (Derakane 510-40A) in ratios of 20, 50 and 80 pph. Two reduced styrene content formulations of Br-VER (30 wt % styrene and 20 wt % styrene) were also prepared. The thermomechanical properties of all seven neat resin formulations were investigated using differential scanning calorimetry (DSC), rheology and dynamic mechanical analysis (DMA). The autocatalytic cure kinetics parameters and chemorheological behavior enable development of a cure cycle for the thermosetting resin. The DMA results demonstrate that all resin formulations comprising Br-VER exhibit improved mechanical performance as compared to the commercial vinyl ester resin.

卤素基阻燃剂通常用于降低可燃性并改善聚合物和纤维增强聚合物复合材料（FRP）的耐火性能。溴化乙烯基酯树脂（Br-VERs）是一类卤化聚合物基体，在经济上可行，是高性能材料，已广泛用于复合材料中以用于特殊应用，例如在海军舰船的船体制造中。在这项工作中，Br-VE聚合物是由四溴双酚A（TBBPA）和甲基丙烯酸缩水甘油酯（GMA）的前体合成的，它们分别来自生物柴油和木浆工业的废物。Br-VE反应产物的分析方法为¹证实了1 H NMR和未反应的（非官能的），单官能的和双官能的TBBPA的存在。将双官能团的Br-VE和苯乙烯（40 wt％）的基准配方与商用溴化乙烯基酯树脂（Derakane 510-40A）以20、50和80 pph的比例混合。还制备了两种降低的Br-VER的苯乙烯含量制剂（30重量％的苯乙烯和20重量％的苯乙烯）。使用差示扫描量热法（DSC），流变学和动态力学分析（DMA）研究了所有七种纯净树脂配方的热机械性能。自催化固化动力学参数和化学流变行为使热固性树脂的固化周期得以发展。
