抄録: Drying and water uptake of poly(acrylic acid)lithium 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 of the release of water molecule bound to two metal carboxylates or carboxyls. Though the equilibrium water uptake increased with increasing neutralization %, the slope of the plot above ca.3396 neutralization was greater than that below this neutralization %. The enhanced water uptake was explained by the appearance of vacant sites in octet coordination of lithium ion.
