Abstract
Stress-strain properties of sulfobetaine polyurethane ionomer based on polyether were studied comparatively to the non-ionic polyurethane an d derived compounds with Pb2+ and Co2+. Sulfonation and treatment with H2S improve the tensile properties due to the increased phase segrega tion and to the semiconducting microphases formed by clustering of met al sulfides, respectively. Complexation with Pb2+ and Co2+ diminishes the tensile properties owing to the partial neutralization of ionic ce nters.
