Zusammenfassung:	The invention relates to filaments, fibers, pulps, films and sheets from a copolyamide which has at least the recurring structural units of the formulae A -OC-AR-CO- B -NH-Ar'-NH- C D and in which the diamine components B, C and D relative to the total amount of diamine components in mol-% are within a predetermined domain. Such copolyamides can be produced from the corresponding diamines and dicarbonyl dichlorides in aprotic solvents in the presence or absence of metal halides of the first or second group of the periodic table. The spinning solutions obtainable therein can be processed in conventional manner into the claimed shaped structures.
