A new ionomer, containing both carboxylated and sufonated groups, was obtained by sulfonating a maleated styrene‐ethylene/butylene‐styrene (m‐SEBS) block copolymer, followed by its neutralization with zinc acetate. Dielectric thermal analyses show that the incorporation of ionic groups in m‐SEBS is responsible for the occurrence of the high temperature ionic relaxation in addition to the relaxations of the base polymer. Formation of the ionomer causes a significant improvement in stress‐strain properties compared to the corresponding base polymer.
