| titleOfInvention | Thermoplastic aromatic polyimide polymer |
| abstract | PURPOSE: To provide the title polyimide polymer having a specific inherent viscosity, excellent in the heat resistance and strength thereof and capable of being injection-molded, by comprising 3,3',4,4'-diphenyl sulfone tetracaboxylic acid dianhydride and a bis(aminophenoxy)benzene. n CONSTITUTION: (A) 3,3',4,4'-Diphenyl sulfone tetracarboxylic acid dianhydride and (B) an aromatic diamine having two connected diphenyl ether bonds [e.g., 1,4-bis(4-aminophenoxy)benzene] are mixed in a solvent to form a polyamic acid solution, which is added to a solution containing acetic anhydride, pyridine, etc., for a reaction thereof to provide the objective polymer containing the repeating units of the formula as a main component and having an inherent viscosity of 0.2W5.0dl/g measured under conditions consisting of a concentration of 0.5g/dl and a temperature of 30°C in concentrated sulfuric acid. n COPYRIGHT: (C)1989,JPO&Japio |
