Permanently coloured aromatic co-polyamides - contg. colour-forming diamines, esp. anthraquinones, for fibres

High-mol. wt. co-polyamides with relative viscosity 1.3-3 (1.4-2.2) (at 20 degrees C as a 0.5% soln. in conc. H2SO4) contain (1) 0.1-15 (0.5-8) moles % of units of formula -HN-A-NH- OC-Ar-CO-, where a is the divalent residue of a colouring diamine and Ar is the divalent residue of an aromatic dicarb...
