An ionomer is a polyelectrolyte that comprises copolymers containing both electrically neutral repeating units and a fraction of ionized units (usually no more than 15 percent). They link in such a way that, even though they are stiff at room temperature, the bonds may be broken down thermally and the new linkages will cause the material to act as though it were a thermoplastic material. Ionomers have unique physical properties including electrical conductivity (see conducting polymer ).
DuPont has recently sold part of their Surlyn line, called Surlyn Reflections to a company called LTL.
