(A) Phase diagrams of the aqueous solutions of the copolymer mixtures with the indicated mix proportions. The transition temperature was determined by the vial-inverting approach. (B) The storage modulus (G′) and loss modulus (G′′) of the aqueous solutions of the copolymer mixtures as a function of temperature. Shear frequency: 1.59 Hz; heating rate: 0.5 ºC /min. The polymer mixture concentration was 25 wt%.
