| titleOfInvention | Production of polyimide compound soluble in organic solvent |
| abstract | PURPOSE: To obtain the titled compound having high heat-resistance, soluble in an organic polar solvent such as general-purpose phenolic solvent, etc., and suitable for the production of a film for high-temperature use, by reacting 3,3',4,4'-benzophenonetetracarboxylic acid with a specific aromatic diamine. n CONSTITUTION: (A) One or more kinds of 3,3',4,4'-benzophenonetetracarboxylic acid and (B) two or more kinds of aromatic diamines of formula [X is O, S, CO, SO 2 , CRR' (R and R' are alkyl, halogen, etc.), etc.] (e.g. the combination of 4,4'-diaminodiphenylmethane and 4,4'-diaminodiphenylsulfone, etc.) are heated in a polar organic solvent (e.g. phenolic solvent). The molar ratio of the component A to B is 0.7W1.3, preferably 1. n COPYRIGHT: (C)1986,JPO&Japio |
