ABSTRACT Flexible polymeric compositions are prepared by introduc- ing sulfonate groups into a plastic polymer and plasticizing the ionomer so formed. Plasticization may be limited to plasticizing the amorphous backbone. Preferably the ionic domains of the ionomer are also plasticized using a plasticizer which is effective at processing temperature but ineffective at use temperature. The compositions of this invention may be used to produce produces which are flexible and have utility as simulated leathers, wire coating insulation, etc.
