The aqueous solution properties of poly ( N-vinyl-2-pyrrolidone ) ( PVP )denaturing agents ( i.e., thiourea, guanidinium chloride, and carbonate ) were studied by viscosity measurements. The polymer dimensions were calculated at 25ЊC and at previously determined theta temperatures. The unperturbed d
Poly(N-vinyl 2-pyrrolidone-g-citric acid) (PVP-g-CA) hydrogels with varying compositions were prepared from ternary mixtures of N-vinyl 2-pyrrolidone-citric acid-water by using 60 Co ␥-rays. The effect of gel composition on the uranyl ions adsorption capacity of PVP-g-CA hydrogels was investigated.
