Ionomers, containing both carboxylate and sulfonate anions on the polymer backbone, based on metal cations like Mg ϩ2 and Ba ϩ2 were prepared by sulfonating maleated styrene-ethylene/butylene-styrene block copolymer, hereafter referred to as m-SEBS, followed by its neutralization by metal acetates.
The dilute solution properties of lightly sulfonated hydrogenated styrenebutadiene-styrene block copolymer (S-SEBS) dissolved in tetrahydrofunan (THF) were studied by viscometry. The ring conformation in dilute regime can be deduced from the intrinsic viscosity data. It is believed that this special
