We present results of dynamic viscoelastic measurements on toluene solutions of telechelic polybutadiene-magnesium ionomer, as one of model systems suitable for a study on structure and dynamics of associating polymers over a wide range of temperature T and polymer concentration C. T dependence of the viscosity is found to be expressed as the product of two contributions, one from local segmental motion and the other from the dissociation-association process of the end ionic groups with the activation energy, Ea≅77kJ/mol.
