    Abstract: Wholly aromatic thermotropic polyesters are based on (A) from 25 to 60 mol % of a mixture of (A1) 4-hydroxybenzoic acid and (A2) 3-hydroxybenzoic acid, 4-aminobenzoic acid and/or 3-aminobenzoic acid or their chlorine, bromine, C1-C8-alkyl or C1-C8-alkoxy derivatives substituted in the nucleus, the molar ratio of A1 to A2 being from 5:1 to 41:1, (B) from 20 to 37.5 mol % of a mixture of (B1) terephthalic acid and (B2) isophthalic acid, the molar ratio of B1 to B2 being from 1.04:1 to 19:1, and (C) from 20 to 37.5 mol % of a mixture of (C1) hydroquinone and (C2) 4,4'-dihydroxydiphenyl, the molar ratio of C1 to C2 being from 0.1:1 to 2.67:1 and the molar ratio of B to C being from 0.9:1 to 1.1:1.
