| abstract | R 3 einen Rest der Formel II bedeutet,n R 4 einen Rest der Formel III bedeutet,n nund R 5 einen Rest der Formel IV und/oder V bedeutet,n nworin Ar 1 eine der für R 2 definierten Bedeutungen aufweist, Y Wasserstoff, ein - Halogenatom, eine Niederalkylgruppe oder eine Niederalkoxygruppe ist, und X ein - Halogenatom, eine Niederalkylgruppe oder eine Niederalkoxygruppe bedeutet, und wobei die Molanteile der wiederkehrenden Struktureinheiten la, Ib, Ic und Id innerhalb ausgewählter Grenzen festgelegt sind. Geformte Gebilde aus den erfindungsgemäßen Copolyamiden zeichnen sich durch gute mechanische Eigenschaften aus.Aromatic copolyamides are described which are soluble in an organic polyamide solvent and which contain recurring structural units of the formulas Ia, Ib, Ic and Id wherein R 1 and R 2 are mainly unsubstituted divalent aromatic radicals, the valence bonds of which are in para- or in a comparable coaxial or parallel position to one another, R 3 represents a radical of the formula II, R 4 represents a radical of the formula III, and R 5 represents a radical of the formula IV and / or V, wherein Ar 1 has one of the meanings defined for R 2 , Y is hydrogen, a - halogen atom, a lower alkyl group or a lower alkoxy group, and X represents a - halogen atom, a lower alkyl group or a lower alkoxy group, and wherein the molar proportions of the repeating structural units la, Ib, Ic and Id are set within selected limits. Shaped structures made from the copolyamides according to the invention are notable for good mechanical properties. |
