The conduction mechanism in the interpolymer complex resulting from the interaction between poly(acrylic acid) (PAA) and polyacrylamide (PAAm) was investigated. The characteristic features of the relation between the logarithm of conductivity, log σ, and 1/ T are different from those corresponding to the individual components of the complex. The value of σ for the complex was found to be less than its corresponding values for PAA or PAAm. The effects of the weight fraction of each polymer and the ionic strength of the solutions on the conductivity of the complex were also studied. The data showed that the σ of the complex depends on the weight fraction of the polymers. © 1998 John Wiley & Sons, Inc. J Appl Polym Sci 68: 2049–2055, 1998
