What is described is a transparent polyamide-imide based on one or more different imido-dicarboxylic acids (AB) or derivatives thereof, and cycloaliphatic diamines (C) comprising 6 to 24 carbon atoms, wherein the imido-dicarboxylic acids (AB) or derivatives thereof are selected from the group of imido-dicarboxylic acids (AB) having the following structural formulas: (see formula I) (see formula II) (see formula III) wherein: ASL = (CH2)5-11, phenylene, (ylomethyl)phenyl, bis(ylomethyl)benzene, cyclohexanediyl, (ylomethyl)cyclohexyl, bis(ylomethyl)cyclohexane, cyclopentanediyl, (ylomethyl)cyclopentyl, bis(ylomethyl)cyclopentane, R = OH, O-alkyl, O-aryl, CI, NH-ASL-COOH, Br, O-(CO)-alkyl, O-(CO)-aryl, R1 = H, methyl, ethyl, propyl, with the provision that the ring can be substituted once or twice, and, with double substitution of the ring, the two substituents can be selected from the group, but may be different, and also moulding compounds based thereon, a method for production, and uses. |
