    Density measurements of poly(acrylic acid) sodium salts

    Density measurements of poly(acrylic acid) sodium salts (PANa) with different degrees of neutralization and water contents are presented. The apparent partial molar volumes of polymer, V 2 ...

    Pulsed NMR study on the hydration of poly(acrylic acid) salts

    Pulsed NMR was applied to measure the spin-lattice (T1) and spin-spin (T2) relaxation times of the equilibrium water absorbed in poly(acrylic acid) lithium salt, sodium salt, and potassium salt. T1 and T2 relaxat...

    Hydration of poly(acrylic acid) lithium salts

    Drying and water uptake of poly(acrylic acid) lithium salts with different degrees of neutralization were studied. Though the equilibrium water uptake increased with increasing neutralization %, the slope of t...

    Hydration of poly(acrylic acid) potassium salts

    Drying and water uptake of poly(acrylic acid) potassium salts with different degrees of neutralization were studied. The slowing down of drying speed in solid state was not due to Tg but due to the difficulty ...
