ABSTRACT:
A method for making a polymer blend composition includes combining at least one component A incorporating at least five percent by weight of anionic functional groups in its structure, at least one component B, preferably free of such functional groups, and at least one component C, which is a metal cation. The method allows for greater flexibility in preparation of polymer compositions than methods previously known.
