Aromatic diamine, process for its preparation and its use |
| abstract |
New aromatic diamines are bis(4-aminophenoxy-benzoyl- or -phenyl-sulphonyl)-phenylindane cpds. of formula (I) wherein X = CO or SO2; R1 Me and R2 = R3 = H; or R1 = R2 = Me and R3 = H; or R1 = Me and R2 = R3 = 1-16C alkyl or aryl; or R1 = Me, R3 = H and R2 = 1-16C alkyl or aryl. USE/ADVANTAGE - (I) are used for polymer prodn. (claimed). They give polyamides with aliphatic or aromatic dicarboxylic acids and polyimides with polybasic aromatic dicarboxylic anhydrides. Aromatic polyimides with two 4-aminophenoxy gps. and a phenylindane gp. are useful as high temp. adhesives for sandwich structures. (I) provide additional diamines for the prodn. of polymers contg.
