Synthesis and dyeing performance of a novel polycarboxylic acid azo dye
A novel reactive polycarboxylic acid dye was synthesized by the reaction of polymaleic anhydride（PMA） with 3-methyl-1-（4- sulfonylphenyl）-4-（4-aminophenylazo）-2-pyrazoline-5-one.The structure of the novel dye was characterized by FTIR,UV-vis and ~（13）C NMR spectra.The dyeing properties of dye on cot...

| Zusammenfassung: | A novel reactive polycarboxylic acid dye was synthesized by the reaction of polymaleic anhydride（PMA） with 3-methyl-1-（4- sulfonylphenyl）-4-（4-aminophenylazo）-2-pyrazoline-5-one.The structure of the novel dye was characterized by FTIR,UV-vis and ~（13）C NMR spectra.The dyeing properties of dye on cotton were tested,and the novel dye possessed high fixation and good fastness. |
