polyazomethines

synonym: poly (Schiff bases)
https://doi.org/10.1351/goldbook.08887
Polymers composed of macromolecules containing azomethine (azanylylidenemethanylylidene) linkages in the backbone: \[\ce{-N=CR-}\] where \(\ce{R}\) is hydrogen, or an alkyl or aryl group (structure-based polymer class name).
Notes:
  1. A polymer with only pendant azomethine groups is excluded.
  2. The name azomethine is derived from the traditional names 'azo' for azanylylidene group \(\ce{-N=}\) and methine' for the methanylylidene group \(\ce{-CH=}\).
  3. The original distinction between polyazomethines and poly(Schiff base)s, which is that a group \(\ce{R}\) in \(\ce{-N=CR-}\) linkage cannot be hydrogen in a polyazomethine but can be hydrogen in a poly(Schiff base), making polyazomethines a subclass of poly(Schiff base)s, has nearly completely disappeared.
