“…25,26 There is a marked difference in the photochemical behavior of aliphatic and aromatic azo compounds. Aliphatic azo compounds usually undergo photodissociation to give free radicals and nitrogen, whereas aromatic azo compounds are stable towards C-N bond scission.…”

“…Molecular weight is determined by osmometry, viscometry, or HPLC (25)(26)(27)(28)(29)(31)(32)(33). Elemental analyses (25)(26)(27)(28)(29), UV spectroscopy (25)(26)(27)29,31,32), derivative UV spectroscopy (35), DSC (36), and 1 H NMR spectroscopy (28,30) are used for determining azo content. The thermal properties of polymers containing side-chain azo groups are similar to those of the low molecular-weight monomers.…”

“…The rate constants and activation energies for (30) and the copolymer of (30) and styrene are given in Table 2. The inclusion of the azo monomers (26) and (27) in a copolymer without decomposition of the azo groups has been achieved via a redox-initiated emulsion copolymerization (25)(26)(27)29,31).…”

“…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.

The terpolymerization of the three monomers (3-vinyl pheny1azo)methylmalodinitrile (l), (3-vinyl pheny1azo)phenylsulfid (2) or 1-(3-vinylphenylazo)-l ,I '-diphenyl methylacetate (3) with methyl methacrylate and butanediol-I ,Cdimethacrylate leads to networks in which the thermolabile azo groups remain intact. Both, the azo monomer and the crosslinking agent are essentially quantitatively incorporated into the network before the conversion of the third monomer is complete. The networks have been characterized in terms of their swelling in benzene, chlorobenzene, and methacrylonitrile. ZUSAMMENFASSUNG:Die Terpolymerisation der drei Monomeren (3-Vinylphenylazo)-methylmalodinitril (l), (3-Vinylpheny1azo)phenylsulfid (2) oder 1-(3-Vinylphenylazo)-l ,I '-diphenylmethylacetat (3) mit Methylmethacrylat und Butandiol-l,4-dimethacrylat fuhrt zu Netzwerken, in denen die thermolabile Azogruppe intakt bleibt. Sowohl das Azomonomere als auch der Vernetzer werden grundsatzlich quantitativ in das Netzwerk eingebaut, ehe die Umsetzung des dritten Monomeren vollstiindig ist. Die Netzwerke wurden beziiglich ihrer Quellung in Benzol, Chlorbenzol und Methacrylnitril charakterisiert.
