“…The synthesis of polymers containing side-chain azo groups has been achieved by modification of a preformed polymer (95)(96)(97)(98)(99)(100)(101), or copolymerization of a monomer having additional azo functionality with a simple monomer such as styrene or methyl methacrylate (102)(103)(104)(105)(106)(107)(108)(109)(110)(111)(112)(113). Many examples of the first method are given in the literature; the modification of cellulose is typical (95). …”

“…The principal purpose for the incorporation of azo functions into the polymer side chains is to produce polymers chemically bound to a dyestuff (93,95,96,(105)(106)(107)(108)(109)(110)113). Such polymers are also good models for studying the mobility of the side chains by photometric methods (103,104,108,109).…”

“…Numerous patents and publications describe possible industrial uses for azocontaining polymers, such as: starting material for block copolymers (1-21); starting material for graft copolymers (22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34); polymeric conductors and semiconductors (53,54,94); polymers with chemically bound dyes (95)(96)(97)(98)(99)(100)(101)(102)(103)(104)(105)(106)(107)(108)(109)(110)(111)(112)(113); and polymers with liquid-crystal properties (89)(90)(91). Azo polymers may find applications in optical data storage and diffractive optical elements due to the formation of surface relief gratings (SRGs) (92,114), which is due to the photoinduced cis-trans isomerization process mentioned above.…”

Azo‐containing polymers (azo polymers) can be formally classified according to a variety of criteria. In this review, the thermal stability of the NN group is the principal criterion. A further subdivision, according to the position of the NN group, is main‐chain azo groups, where each monomer unit contains a stable or unstable azo function or in copolymers in which one component contains an azo group, vs. side‐chain azo groups, where each monomer contains an azo group or in copolymers in which one component contains an azo function.

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 color shades with good to very good depth and levelness on the fiber. The dyeing of the monomeric dyes shows good fastness to light and very good to excellent fastness to washing, perspiration, sublimation, and solvents. The corresponding polymeric dyes show excellent fastness properties. The percentage dyebath exhaustion and fixation on the fiber have been found to be good to very good (60 -90%).
