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
The extent of colour development in an aqueous poly(vinyl alcohol) (PVA)Γiodine complex solution increased with increasing syndiotacticity up to a certain syndiotactic content, then decreased with increasing syndiotacticity. The complex formation depended on the content of the syndiotactic pentad se
## Abstract The desorption behavior of iodine in syndiotactic poly(vinyl alcohol) (__s__βPVA) with a syndiotactic diad content of 63.1% iodine film in water was investigated in relation to the solubility of __s__βPVA in water. Despite a low numberβaverage degree of polymerization of 900, the degree
