Wholly aromatic liquid-crystalline condensates which form a liquid-crystalline fiber-forming melt below 320 DEG C. and are diphase within the range from the glass transition temperature Tg to the melting point and are composed of (a) not less than 10 mol % of repeat units of the formula I <IMAGE> I (b) from 5 to 30 mol % of repeat units of the formula II <IMAGE> II (c) from 0 to 20 mol % of one or more of the repeat units of the formulae III, IV or V <IMAGE> III <IMAGE> IV <IMAGE> V (d) from 0 to 20 mol % of one or more of the repeat units of the formulae VI, VII, VIII or IX <IMAGE> VI <IMAGE> VII <IMAGE> VIII <IMAGE> IX (e) a molar amount corresponding to the total amount of components (b), (c) and (d) of repeat units of the formula X <IMAGE> X the mole percentage of components (a), (b), (c), (d) and (e) adding up to 100 mol % in each case, the preparation thereof and filaments, fibers, films, moldings and surface coating prepared therefrom.
