Abstract

Procedure for the preparation of N-aryl-substituted linear polyamides, endowed with high molecular weight, comprising the following repeating unit **(See formula)** in which Y is the radical of an aromatic diamine that has the structure: **(See formula)** where Ar is the divalent aromatic carbocyclic radical; R is a monovalent aromatic radical, X is H or a monovalent aromatic radical and E is a divalent heterocyclic aromatic radical, characterized in that 1,2,5-thiadiazole-3,4-dicarboxylic acid dihalide is condensed, in a hydrocarbon solvent or in a chlorinated hydrocarbon solvent, with an aromatic diamine having the General Formula **(See formula)** where Ar, R, H and E have the meaning indicated above or their mixtures.
