- 1 - A B S T R A C T HOE 87/F 397 Filament-, fiber- or film-forming aromatic copolyamides, preparation and use thereof Filaments, fibers and films from aromatic copolyamides (polyaramids) of the dicarboxylic acid/diamine type of at least four aromatic monomeric compounds of A', B', C' and D' which each contain a group of the following formulae: A: -CO-Ar-CO- B: -NH-Ar1-NH- C: -NH-Ar2-NH- D: -NH-Ar3-Z-Ar3-NH- and processes for their preparation and possible appli- cations. Filaments, fibers and films having a high elongation at break and a high initial modulus are obtained using easily accessible monomers and polyaramids synthesized therefrom which are highly soluble in organic solvents.
