FLEXIBLE POLYMERIC COMPOSITIONS COMPRISING A NORMALLY PLASTIC POLYMER SULFONATED TO ABOUT 0.2 TO ABOUT 10 MOLE SULFONATE

摘要

Flexible polymeric compositions are prepared by introducing 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.
