'''Polyether block amide''' or '''PEBA''' is a [[thermoplastic elastomer]] (TPE). It is also known under the tradename of PEBAX ([[Arkema]]). It is a [[block copolymer]] obtained by [[polycondensation]] of a carboxylic acid [[polyamide]] ([[Nylon 6|PA6]], [[PA11]], [[polyamide 12|PA12]]) with an [[alcohol]] termination polyether ([[PTMG(Polytetramethylene glycol )]], [[Polyethylene glycol|PEG]]). The general chemical structure is:

:[[Hydrogen|H]][[Oxygen|O]] - ([[Carbon|C]][[Oxygen|O]] - '''[[Polyamide|PA]]''' - [[Carbon|C]][[Oxygen|O]] - [[Oxygen|O]] - '''[[Polyether|PE]]''' - [[Oxygen|O]])_n - [[Hydrogen|H]]
