The invention relates to bis(aniline) compounds containing multiple arylethynyl, alkylethynyl, ethynyl groups or their combinations, processes of making such compounds and materials comprising such compounds. Such, bis(aniline) compounds preferably comprise multiple phenylethynyl (PE) groups, i.e. 2-4 PE moieties. Such compounds are useful monomers for the preparation of polyimides, polyamides and poly(amide-imides) whose post-fabrication crosslinking chemistry (i.e. reaction temperature) can be controlled by the number of PE per repeat unit as well as finding utility in thermosetting matrix resins, 3D printable resins, and as high-carbon-content precursors to carbon-carbon composites.
本发明涉及包含多个芳基乙炔基、烷基乙炔基、乙炔基团或其组合的二(苯胺)化合物,制造此类化合物的过程以及包含此类化合物的材料。这样的二(苯胺)化合物优选包含多个苯乙炔基(PE)团,即2-4个PE基团。这类化合物是有用的单体,用于制备聚酰亚胺、聚酰胺和聚(酰胺-亚胺),其制品后的交联化学(即反应温度)可以通过每个重复单元中的PE数量来控制,并且还用于热固性基体树脂、3D打印树脂,以及作为高碳含量碳-碳复合材料的预聚物。
