[en] Alkaline earth alpha,omega-dicarboxylatopolybutadienesd issolved in a nonpolar solvent (an= 4600) display an attractive thermorheological simplicity and exhibit a secondary relaxation characteristic of the ionic component. The shear-thickening character of these solutions is to be outlined. Their deformation mechanism is controlled by the stability and the mean size of the ionic multiplets formed by the carboxylate end groups. The electrostatic origin of the viscoelastic behavior observed is well established by its dependence on solvent, temperature, and cation size.
