| abstract | The invention relates to aromatic copolyamides which are soluble in organic polyamide solvents and contain the recurring structural units of the formulae Ia, Ib, Ic and optionally Id: [-OC-R<1>-CO-NH-R<2>-NH-] (Ia) <IMAGE> [-OC-R<1>-CO-NH-R<3>-NH-] (Id) where R<1> and R<2> are principally unsubstituted divalent aromatic radicals whose valence bonds are in the para-position or in a comparable coaxial or parallel position to one another, X is a group of the formula -S-, -SO2-, -CO- or -O-, Y has one of the definitions given for X, R<3> is a radical of the formula II, of the formula III, of the formula IV and/or of the formula V <IMAGE> in which Hal is a halogen atom, and R<4> is C1-C6-alkyl, C1-C6-alkoxy or halogen, and where the molar proportions of the recurring structural units Ia, Ib, Ic and Id are fixed within selected limits. Shaped articles made from the copolyamides according to the invention are distinguished by good mechanical properties; in particular, fibres can be produced which have extremely high tear strengths and knot strengths. |
