| titleOfInvention | Imide group-containing aromatic polyamides, process for their preparation and use thereof as molding materials |
| abstract | ABSTRACT OF THE DISCLOSURE An imide group-containing aromatic polyamide, obtained by polycondensation of A) an aromatic diamine of the general formula H2N-Ar-O?Ar'-X-Ar'??O-Ar-NH2 wherein Ar and Ar' are a m- or p-phenylene group, X is -SO2- or -CO- and m is 0 or 1, with at least one aromatic dicarboxylic acid B) selected from the group consisting of B1) a mixture comprising 40 to 100 mole % of an acid of the structure and 60 to 0 mole % of an acid of the structure in which n is 0-4 and R is selected from the group consisting of a) an alkyl group having 1-6 carbon atoms, b) an unsubstituted phenyl or an alkyl- or aryl substituted phenyl group, c) an alkoxy group having 1-6 atoms, d) a phenoxy group, in which the phenyl ring is unsubstituted or is alkyl- or aryl substituted, and e) a halogen, B2) an acid of the structure and B3) a dicarboxylic acid of the formula HO2C-Ar-(A-Ar)p-CO2H wherein Ar is m-phenylene or p-phenylene, A = -O-, -S-, -SO2-, or -CO-, and p = 0 or 1, and C) an aromatic dicarboxylic acid anhydride of the formula in which R and n are as defined above. The polyamide has good processability and is useful as a molding material. |
