Abstract: - 16 - O.Z. 0050/38141 Wholly aromatic mesomorphic polyester imides which form a liquid-crytalline fiberforming melt below 320.degree.C and are composed of a) from 5 to 35 mole % of repeat units of the formulae I and/or II I II where the Xs and n's can be identical or different, each X being -O-, -S-, -SO2-, -CO-, -CH2- or =C(CH3)2 and n being 0 or 1, b) from n to 30 mole % of repeat units of the formulae III and/or IV III IV c) a molar amount corresponding to the total amount of components a and b of one or more of the repeat units of the formulae V, VI, VII or VIII V VI - 17 - O.Z. 0050/38141 VII VIII d) not less than 10 mole % of repeat units of the formula IX IX e) if desired from 5 to 25 mole X of repeat units of the formula X X the molar proportions of components a, b, c, d, and e adding up to 100 mole % in each case, and the preparation thereof.
