| 概要 |
Soluble polyimides with aliphatic structure were prepared by reactions of 2,3,5-tricarboxycyclopentyl acetic dianhydride (TCA-AH) with aromatic diamines, or aromatic tetracarboxylic dianhydrides and a...lkyl diaminobenzophenone (ADBP). The two-step polymerization systems including poly(amic acids) synthesis and solution imidization using pyridine and acetic anhydride gave soluble polyimides with high imidization ratios. These polyimides exhibited high thermal stability in air and nitrogen, and good solubility in common polar solvents such as NMP (N-methyl-2-pyrrolidone).続きを見る
