Microstructure of polyurethane ionomers derivatized with dodecylamine and polyethylene oxide in the hard segment

Abstract Segmented polyether‐polyurethanes containing sulfonate groups in the hard segment were modified by the grafting of polyethylene oxide and C 12 hydrocarbon chains. The grafts were attached via the sulfonate groups. The physical properties of the materials, including stress–strain behavior, thermal behavior, and water uptake were studied. Grafting was found to alter material behavior significantly. Both the alkyl and polyethylene oxide …
