Poly(methacrylic acid‐co‐methacrylamide) and poly(acrylic acid‐co‐acrylamide) have been synthesized and characterized by known methods. The respective comonomer units of the two copolymers enter into complex formation through hydrogen bonding and ion‐dipole interactions. The unreacted units in the intercopolymer complex also interact with homopolymers such as poly(N‐vinylpyrrolidone) and poly(oxyethylene) as well as transition metal ions to form three and four component intermacromolecular complexes. Formation of these complexes could be shown through several experimental techniques, e.g. viscometry, conductometry, potentiometry, IR and UV spectrophotometry.
