Abstract: The effect of degree of polymerization on the crystallizability of poly (vinyl alcohol) (PVA) have been studied about the cased films of PVAs with various degrees of polymerization by measuring their absorbance of crystallization-sensitive band, 8.7 \sim\ (1141 cm-1) and specific gravity. It was thus observed that the crystallizability of PVAs apparently increased in lower degrees of polymerization than 300\sim\500, while it remained nearly constant in higher than 500.
