The rheological properties of aqueous solutions of poly(methyl vinyl ether-co-maleic anhydride) (PMVE-MA) upon addition of metallic cations at different pH values were investigated. Sol-gel transition and shear-thickening phenomena at moderate shear rate were observed upon increasing the amount of metallic cations, especially for cupric cation. At certain molar ratio (fgel) of added cupric cations...
