The effect of the dissolved state of poly(vinyl alcohol) (PVA) molecules in water on the color development due to PVA-iodine complexes was investigated at each given PVA and iodine concentration using two kinds of syndiotactic-rich PVA (S-PVA) which are unstable in water because of the formation of
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
