An aromatic polycarbodiimide comprising a structural unit represented by the following formula (I):
where R is an organic group having 3 or more carbon atoms, and n is an integer of 2 to 300,
and a polycarbodiimide solution, a polycarbodiimide sheet, and an insulated coated electric wire which are prepared using the aromatic polycarbodiimide. The aromatic polycarbodiimide has high solubility in an organic solvent, satisfactory workability, and excellent heat resistance and humidity resistance. The insulated coated electric wire has excellent durability and is highly reliable under high pressure, high humidity conditions.
一种芳香族聚碳二亚胺,包含下式(I)所代表的结构单元:
其中 R 是具有 3 个或更多碳原子的有机基团,n 是 2 至 300 的整数、
以及使用芳香族聚碳二亚胺制备的聚碳二亚胺溶液、聚碳二亚胺薄片和绝缘涂层电线。芳香族聚碳二亚胺在有机溶剂中的溶解度高,可加工性好,耐热性和耐湿性极佳。绝缘涂层电线具有出色的耐久性,在高压、高湿条件下也非常可靠。
