Abstract
Two phenolic copolymers and a methacrylic acid-methacrylamide copolymer have been synthesized and characterized by known methods. The co-ordinating groups of the respective copolymers form complexes through hydrogen bonding and ion-dipole interactions. The unreacted functional groups of the intercopolymer complexes undergo further complex formation with poly(vinylpyrrolidone) and a transition metal ion (e.g. Cu 2+). The different stages in the interactions have been studied by several experimental techniques, e.g. viscometry, potentiometry, conductometry and i.r. and u.v. spectrophotometry. Formation of multicomponent complexes with distinct stoichiometries have been predicted, and some schemes have been suggested to explain the mode of interaction between the components.
