ABSTRACT OF THE DISCLOSURE: Disclosed are wholly aromatic mesomorphic poly- ester amide imides which form a liquid-crystalline fiber- forming melt below 320°C and are composed of: a) from 5 to 35 mol% of repeat units of the formula (I) and/or (II): Image (I) Image (II) where X can be identical or different, each X being -O-, -S-, -SO2-, -CO-, -CH2- or =C(CH3)2, and n is 0 or 1, b) from 0 to 30 mol % of repeat units of the formulae (III) and/or (IV): Image (III) Image (IV) c) a molar amount corresponding to the total amount of components a) and b) of one or more of the repeat units (V), (VI), (VII), (VIII), (IX) or (X) in an amount of: c1) from 3 to 35 mol % of units of the formula (V): Image (V) c2) from 0 to 10 mol % of units of the formula (VI): Image (VI) c3) from 2 to 25 mol % of units of the formula (VII): Image (VII) c4) from 2 to 20 mol % of units of the formula (VIII): (VIII) Image c5) from 0 to 20 mol % of the units of the formula (IX): Image (IX) c6) from 2 to 20 mol % of units of the formula (X): Image (X) with the provisos that at least one of the repeat units of formulae (VI) or (VII) is allways present in the composition and that the total of the mole percentages of components c1), c2), c3), c4), c5) and c6) equals in each case the total of the mole percentages of components a) and b); d) not less that 10 mol % of repeat units of the formula (XI): Image (XI) e) from 0 to 25 mol % of one or more of the repeat units of the formula (XII), (XIII) or (XIV): Image ( X I I ) Image ( X I I I ) Image (XIV) the mole percentages of components a), b), c), d) and e) adding up to 100 mol % in each case. Also disclosed are the preparation thereof and fibers, films and moldings prepared therefrom.
