Summary

The determination of acid end-groups of acrylamide and acrylonitrile polymers initiated by cerium (IV)-malonic acid, cerium (IV)-tartaric acid and cerium (IV)-citric acid redox initiators systems was made in aqueous and nonaqueous media potentiometrically. The effect of solvent, titrant and electrode system on the half-neutralization potentials and number-average molecular weights, \(\overline {M_n } \), were determined potentiometrically and were studied. These \(\overline {M_n } \) values were compared with those obtained by viscosimetric and conductometric methods.
