Poly(N-vinyl 2-pyrrolidone/acrylic acid) [P(VP/AA)] polyelectrolyte networks were prepared from the ternary mixtures N-vinyl 2-pyrrolidone/acrylic acid/ water by using ␥ rays at ambient temperature. Equilibrium swelling behavior of these hydrogels was studied using an equation, based on the James-Gu
## Abstract Poly acrylic acid (PAA) and its stoichiometric complexes with trivalent rare earth (RE) have been synthesized and well characterized by means of elemental analysis, IR, TG‐DTA, fluorescence spectra, etc. Chemical analysis indicated that the molar ratio of COO^−^ and RE^3+^in the comple
