de (HPI) moiety which was incorporated into the polyester chain by copolymerization. These copolyesters, as a result, exhibit high efficiency in retarding decomposition by capturing the decomposed products, particularly for the carbonyl‐terminated fragments, thus increasing the fire‐safety properties, such as self‐extinguishing, anti‐dripping, and inhibiting heat release and smoke production. The successful
聚酯在加热时分解成小分子,主要通过酯键的断链作用释放出易燃的挥发物和有毒气体,因此防火性能差,从而限制了它们的应用。本文报道的是由N的热重排产生的(双)恶唑啉基团对末端基团的捕获作用-(2-羟苯基)邻苯二甲酰亚胺(HPI)部分,通过共聚结合到聚酯链中。结果,这些共聚酯通过捕获分解产物(特别是对于羰基封端的片段)表现出高效率来阻止分解,从而提高了防火性能,例如自熄,防滴落,抑制热量释放和烟雾产生。该方法在半芳族和脂族聚酯中的成功应用为设计通用的防火聚合物提供了广阔的前景。
