The cathode potential for Cu deposition was greatly polarized in solutions containing both Cl- and gelatin or PEG, showing evident synergistic effect of polymer additives and Cl- on Cu deposition. The rotating ring-disk electrode technique revealed that Cu deposition in solutions containing small amounts of Cl- proceeded with initial formation of adsorbed intermediate CuClad. The Cole-Cole plots obtained by AC impedance techniques suggest that the reduction of CuClad is suppressed by polymer additives. The polarization caused by the additives gradually decreased with increasing the electrolysis duration. Gel permeation chromatography showed that the molecular weight of gelatin in electrolyte decreased with increasing the electrolysis duration. The decrease in molecular weight of gelatin by electrolysis brought about the shift of the cathode potential to the more noble direction, showing that the molecular weight of degraded gelatin was related to the deposition potential of Cu.
