Polyamides pyridine groups

An early example of a monosubstituted stilbene was introduced by Geigy as Tinopal RBS (89) and used for cotton and polyamide (nylon). Conversion of the sulfonic acid group into A-ethylsulfonamide, via the sulfonyl chloride, yields an FBA for polyester and plastics (55USP2713057). The triazole ring is formed by diazotization of the 4-aminostilbene followed by coupling with 2-naphthylamine and oxidation with ammoniacal copper(II) sulfate, occasionally in pyridine (21CB2191). [Pg.338]
