1. A biocompatible polymer system comprising at least one polymer, said polymer comprising (i) a plurality of pores and (ii) a sulfonic acid salt functionality;
wherein the polymer's pore structure has a total volume of pore sizes in the range of from 10 Å to 40,000 Å greater than 0.1 cc/g and less than 5.0 cc/g dry polymer; and
wherein the polymer is in the form of a crosslinked polymer or a porous polymer; wherein the crosslinked polymer or porous polymer has been sulfonated under mild conditions that retain residual functionality of any unreacted double bonds and chloromethyl groups.
