From a set of around 30 thermosets (polycyanurates, polybenzoxazines, epoxy and phtalonitrile resins) tested in pyrolysis-combustion flow calorimetry, the contributions to flammability of 14 new chemical groups are calculated using a method previously proposed and validated. The flammability properties include total heat release, heat release capacity and char content. The comparison between these groups allows drawing some consistent conclusions about the best structures in terms of flammability. Especially, the aromaticity, the number of covalent bonds between the considered chemical group and the neighboring groups and the presence of heteroatoms (O, N) in the structure are highlighted.

从一组约30种热固性材料（聚氰尿酸酯，聚苯并恶嗪，环氧和邻苯二甲酸酯树脂）中进行热解-燃烧流动量热测试，使用先前提出并验证的方法计算了14种新化学基团对可燃性的贡献。可燃性包括总热量释放，热量释放能力和炭含量。这些组之间的比较允许就可燃性方面的最佳结构得出一些一致的结论。特别是，突出了芳香性，所考虑的化学基团与相邻基团之间的共价键数以及结构中杂原子（O，N）的存在。
