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.
