随着石油资源的枯竭，作为石油衍生乙烯基酯树脂替代品的生物基乙烯基酯树脂的开发激发了研究人员的兴趣。然而，具有良好的热机械性能、阻燃和抑烟性能的生物基乙烯基酯树脂的开发还处于起步阶段。本工作以可再生香兰素为原料，通过两步反应合成了具有席夫碱结构的生物基乙烯基酯树脂单体(((oxybis(4，1-phenylene))bis(azaneylylidene))bis(methaneylylidene))bis(2-methoxy-4，1-phenylene)bis(2-methylacrylate)。将该单体与苯乙烯固化得到生物基乙烯基酯树脂(OBBMA体系)，并与石油基乙烯基酯树脂(VER901)进行了比较。OBBBMA系统的ATGAS高达185.3°C，远高于VER901(127.1°C)。在氮气中，OBBBMA体系的残炭是VER901体系的14倍。与VER901相比，OBBBMA系统的放热率峰值、产烟率峰值、总排烟量和CO产生量分别降低了51%、48.6%、49.7%和55%。OBBBMA体系表现出高玻璃化温度、良好的阻燃和抑烟性能，在高性能应用中显示出巨大的潜力来取代石油衍生的乙烯基酯树脂。
With the depletion of petroleum resources, the development of biobased vinyl ester resins as an alternative to petroleum-derived vinyl ester resins inspires researchers. However, the development of biobased vinyl ester resins with good thermal-mechanical properties, flame retardancy, and smoke suppression is in its infancy. In this work, the biobased vinyl ester resin monomer (((oxybis(4,1-phenylene))bis(azaneylylidene))bis(methaneylylidene))bis(2-methoxy-4,1-phenylene)bis(2-methylacrylate) (OBBBMA) with a Schiff base structure was prepared from renewable vanillin via a two-step reaction. The monomer was cured with styrene to obtain biobased vinyl ester resin (OBBBMA system), and the OBBBMA system was compared with the petroleum-derived vinyl ester resin (VER901). The OBBBMA system possesses aTgas high as 185.3 °C, which is much higher than that of VER901 (127.1 °C). The char residues of the OBBBMA system are 14 times that of VER901 in N2. Compared to VER901, the peak of heat release rate, the peak of smoke production rate, total smoke production, and CO production of the OBBBMA system decreased by 51, 48.6, 49.7, and 55%, respectively. The OBBBMA system shows a highTg, good flame retardancy, and smoke suppression and exhibits great potential to replace the petroleum-derived vinyl ester resin in high-performance applications.
