- Polyamides are formed by linking bi-functional monomers with amino groups and, preferably activated, carboxyl groups. Both diamines with dicarboxylic acids and amino acids with amino acids can be reacted. In the latter, with the amino group and the carboxyl group, both functional groups required for linking are present in the same molecule.
- lactams such as e-caprolactam, e.g. be used by Ringöffhungspolymerisation for the production of polyamides.
- E-Caprolactam is industrially produced from cyclohexanone and laurolactam from cyclododecanone , This is the ketone first to the oxime and this oxime then again by a Beckmann rearrangement to lactam, so the monomer for the polyamide preparation implemented.
- Bio-based polyamides available in industrial quantities have hitherto been produced predominantly on the basis of castor oil.
- the monomers produced from fatty acids lead to
- linear, semi-crystalline polymer chains (PA11, PA410, PA610, PA1010, PA10.12) with comparable properties to fossil-based polyamides.
