A poly-Schiff base consisting of an alternating double bonds chain, having side groups capable of forming complex salts, has been synthesized. Electrical conductivity measurements at room temperature at different times were performed on the original polymer and on its complex salts with Ni, Cu, Co, Cr. It appears that complex salts have an electrical conductivity that is lower by one or two order of magnitude than that of the original polymer. Furthermore the electrical conductivity of both polymer...
A study on the basicity and complexing ability of some poly(amidoamines) and their low-molecular weight analogues has been performed in aqueous solution. “Real” basicity constants have been determined for the polymers. This unusual behaviour has been attributed to their particular structure. The basicity constants of the polymers are always slightly lower than those of the corresponding models. The complexing ability of both macromolecules and models towards Cu(II) and Ni(II) ions in aqueous solution...
