Classification
According to the composition of their main chain, polyimides can be:
Aliphatic (linear polyimides),
Semi-aromatic,
Aromatic: these are the most used polyimides because of their thermostability.
According to the type of interactions between the main chains, polyimides can be:
Thermoplastic: very often called pseudothermoplastic.
Thermosetting: commercially available as uncured resins, polyimide solutions, stock shapes, thin sheets, laminates and machined parts.
