METAL-POLYELECTROLYTE COMPLEXES X, THE POLY-NVINYLIMIDAZOLE-ZN II COMPLEX The binding of Zn by poly-N-vinylimidazole in 1M NaNO3 at 0.01 and 0.10 M polymer concentrations showed fourfold coordination. TURBIDOMETRIC STUDY OF THE POLY-N-VINYLIMIDAZOLE-Zn II COMPLEX Results indicated that the polymer chain association occurred during the complex formation, with the metal ion acting as cross-linking agent. CATALYTIC STUDIES OF THE DEHYDRATION OF H2CO3 The ZnII-poly-N-vinylimidazole complex gave no additional contribution. The catalytic effect of the poly-N-vinylimidazole was estimated in the order of 100 times that of imidazole.
