When these substances are dissolved into a solvent, they produce ionicspecies havinglargemolecularweightsandtheir counterions. We knowa variety of naturally occurring ionic polymers and chemically synthesizedc- pounds. Examples of the former are nucleic acids and some proteins, which playanimportantroleinbiologicalsystems. Examplesofsyntheticionicpo- mers are polyacrylic acid (PAA), polystyrenesulfonic acid (PSS) and poly- lylamine (PAAm).

When PAA is dissolved in a dissociating solvent like water, anionic macroions and counterions are produced. In the following scheme, the counterions are protons but they may + be metal cations such as Na : CH CH CH CH 2 2 + + mH COOH COO m m PAA PAA anion Counterions.
