Compositions, solid polymeric compositions, and/or articles of manufacture are provided that can include a polymer matrix having a plurality of ion-exchange particles distributed therein. Products by process are provided that can include prior to solidifying the polymeric precursors, blending the precursors with ion-exchange particles to form a mixture, and solidifying the mixture to form a solid polymeric composition product. Solid polymeric composition production methods are also provided that can include providing a plurality of ion-exchange particles, prior to solidifying the polymeric precursors, blending the precursors with the ion-exchange particles to form a mixture, and solidifying the mixture to form a solid polymeric composition. Article of manufacture production methods are provided that can include incorporating a solid polymeric composition into an article of manufacture, the solid polymeric composition including a polymer matrix and a plurality of ion-exchange particles distributed therein.
