The technique of thin-layer chromatography has been applied to the separation of poly (vinylalcohol) (PVA) from biological materials. A mixture of boric acid and iodine solution was used as the detection reagent. A solvent mixture of propanol-water was, effective in separating on silica gel, and 30% perchloric acid in separating on kieselgur in the presence of starch. The R<SUB>f</SUB> value was unaltered by changes in degree of polymerization (5002, 000). The R<SUB>f</SUB> value of fully hydrolysed PVA was higher than that of partially hydrolysed PVA with 30% perchloric acid on kieselgur.
