ABSTRACT:
The invention provides secondary sulfonamide polymers, wherein some, most, or all of the sulfonamido protons have been replaced with a substituent other than hydrogen. The invention also provides methods for preparing such polymers as well as devices (e.g. composite membranes) incorporating such membranes.
