'''Polyethylene amine''' is a [[polymer]] of [[aziridine]] with the molecular formula (CH<sub>2</sub>CH<sub>2</sub>NH)<sub>n</sub>. It is a structural analogue of [[polyethylene glycol]] with -NH- in place of oxygen atoms. It is produced by the polymerization of aziridine.
Oligomeric polyethylene amines with a small number of units are used as [[curing]] agents for [[epoxy resin]]s. They are water-soluble. The gelling properties of higher polyethylene amines are useful for resin formulas that require high [[viscosity]] during application and curing.
Polyethylene amine can form [[gel]]s. Due to the rich content of easily protonated amine groups, in acidic solutions it behaves as a [[polyelectrolyte|polycation]].
Polyethylene amine may have applications as a component of [[ion exchange resin]]s.
High selectivity semipermeable membranes, permeable for [[carbon dioxide]] and retaining [[oxygen]], can be made from this material as well. These are important for life support systems. [http://www.dsls.usra.edu/meetings/bio2001/pdf/EVAcomplete.pdf]
