trolytes and Transition Metal Ion Interaction

Some random three-component copolymers have been prepared by condensing offormaldehyde with various aromatic amines. The compositions of the copolymershave been determined by known methods. Selective complexation of copolymers have been carried out with PAA, PEI, PVP and some transition metal ions (e.g., Cu2+) by adding the components in various sequences. The relative complexation ability of differ-ent-NH2 groups, associated with the various comonomer units, has been interpreted in terms of the nature of substituents present at the para position of the comonomer units. The formation of these complexes has been studied by conductometry, potentiometry and viscometry techniques. A scheme has been presented to explain the mode of inter-action of the various components
