The kninetics of acid-catalyzed acetalization and ketalization of poly(viny1 alcohol) (PVA) were systematically studied in completely homogeneous media with carefully selected solvents. Thus the acetalization reaction was run in water with six aldehydes [RICHO (R, = H, CH3, CZH5, n-C3H7, i-C3H7, CIC
The sorption and the permeation of iodine in water-swollen poly(viny1 alcohol) (PVA) membranes and the formation of PVA-iodine complexes were studied. The logarithms of the permeability and the diffusion coefficient decreased approximately linearly with the increase in polymer volume fraction. When
