An aromatic polyamide, which is obtained by reacting a benzene tricarboxylic acid or a derivative thereof with a diamine compound in the presence of a terminally blocked compound having a crosslinkable group and a functional group that is reactive with a benzene tricarboxylic acid such as 1-amino-2-propanol or a derivative thereof as expressed by scheme (1), and which has a weight average molecular weight of 1,000-100,000 in terms of polystyrene as determined by gel permeation chromatography, has good solubility in organic solvents, while maintaining heat resistance and transparency. A thick film can be formed using a film-forming composition that contains this aromatic polyamide.
一种芳香族聚酰胺,通过在末端阻断化合物的存在下,将苯三羧酸或其衍生物与一种含有可交联基团和与苯三羧酸反应的官能团的二胺化合物反应而获得,例如1-氨基-2-丙醇或其衍生物,如图1所示。其相对于聚苯乙烯的重均分子量在1000-100000之间,通过凝胶渗透色谱法测定。该聚酰胺在有机溶剂中具有良好的溶解性,同时保持耐热性和透明度。使用含有该芳香族聚酰胺的成膜组合物可以形成厚膜。
