Sulfonated polyphosphazenes, uses thereof, and methods for preparing same

摘要

Polyphosphazene polymers having at least one sulfonated pendent group, and no more than five different sulfonated pendent groups, repeated along the polymer chain, wherein at least one the repeated sulfonated pendent groups links at least one SO3<-> group to the polymer chain through a nitrogen-free linkage containing at least three carbon atoms, are disclosed, along with methods of making same, and uses therefor.
