Abstract
New polymer compositions based on poly(2,6-dimethyl-1,4-phenylene oxide) and other high-softening-temperature polymers are disclosed. These materials have a microphase domain structure that has an ionically-conductive phase and a phase with good mechanical strength and a high softening temperature. In some arrangements, the structural block has a softening temperature of about 210° C. These materials can be made with either homopolymers or with block copolymers. When these polymers are combined with electrolyte salts, they can be used as electrolytes that have both high ionic conductivity and good mechanical properties.
