Oxidatively stable rigid aromatic polyimide compositions and process for their preparation |
摘要 |
A rigid, aromatic polyimide composition prepared using a solution imidization process from an aromatic tetracarboxylic dianhydride and a diamine which is greater than 60 mole % to about 85 mole % p-phenylene diamine and 15 mole % to less than 40 mole % m-phenylene diamine exhibits exceptional tensile properties and thermal oxidative stability.
