## 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

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 To precisely identify the effect of blend ratios of syndiotacticityβrich poly(vinyl alcohol) (sβPVA)/atactic PVA (aβPVA) on the water stability of sβPVA/aβPVA/iodine complex blend films, we prepared two PVAs with similar numberβaveraged degrees of polymerization of 4000 and degrees of s
## Abstract To enhance durability of poly(vinyl alcohol) (PVA)/iodine polarizing film under humid and warm atmospheres and to identify the effects of syndiotacticity on the polarizing efficiency (PE) and durability of PVA/iodine complex film, we prepared three high molecular weight (PVA)s with simi
