Studies of novel monomeric and polymeric azo disperse dyes

Abstract: A series of polymeric dyes were synthesized by free-radical addition polymerization of monomeric dyes that were derived from diazotized 2-amino-3,5-bis-(ethoxycarbonyl)-4-methylthiophene by coupling with various N-arylmaleimides. All the polymeric dyes were characterized by elemental analysis, IR and visible spectroscopy, viscometry, and TGA. Color and dyeability of the polymeric dyes are discussed by comparing them with those of the corresponding monomeric dyes. All the dyes have been found to give various co… Show more

“…They have been used as textile dyes due to excellent performance properties such as leveling, fastness to light and wet treatments, and very good thermal and chemical resistance. They also impart very bright colours [3][4][5]. Other outlets for these dyes are in food coloration, surface coatings, hair dyes [6], solid state laser dyes [7], and jet printing [8,9].…”

“…Copolymerization with methyl methacrylate as well as homopolymerization of each dye monomer yielded linear soluble polymers. A different approach is the performance of azo coupling with N-aryl maleimides for the generation of radically polymerizable azo dye derivatives [53,54]. For the preparation of structurally different azo dyes, 2,6-dibromo-4-nitroaniline (see Scheme 1) and 2-amino-3,5-bis(ethoxycarbonyl)-4-methylthiophene were converted into the corresponding diazonium salts.…”

“…Various polymeric dyes have been developed by incorporating hydrophilic or hydrophobic chromophores onto a variety of polymers, including polyallylamine, polyethylene polyamine and polyvinylamine . Tang et al invented a polymeric dye by reacting polyallylamine with 2,4‐dinitrochlorobenzene, and achieved a fixation of 99% to cotton and silk with a crosslinking agent.…”
