- W1489427758 abstract "Des oligoamides à groupes terminaux NH2 ont été modifiés par réaction avec des chlorures d'acide de colorants de type azoïque ou quinophtalone. Des oligoamides à groupes terminaux nitro-4 phényles ont été réduits en oligoamides à terminaisons amino-4 phényles puis diazotés et copulés avec le β naphtol. Les oligoamides colorés porteurs de fonctions azoïques ont une stabilité thermique trop faible pour pouvoir être filés; par contre, ceux dont les chromophores sont des groupes quinophtalones peuvent servir de colorants macromoléculaires pour le polyamide −6,6. Les fibres colorées obtenues ont une stabilité totale vis-à-vis des solvants. Oligoamides with amino end-groups have been reacted with acid chlorides of azo or quinophthalic dyes. Oligoamides with 4-nitro phenyl end-groups have been reduced to oligoamides with aminophenyl end-groups; they have been diazotized and coupled with β naphthol. Due to their low thermal stability, oligoamides containing azo groups cannot be spun; on the other hand, oligoamides with quinophthalic groups can be used as macromolecular dyes for polyamides. Coloured fibres have excellent mechanical properties and the dye cannot be extracted by solvent." @default.
