Effect of inorganic salts on the crystallinity of polyvinyl alcohol

Journal of Applied Spectroscopy Aims and scope

We use IR spectroscopy to study the crystallinity of polyvinyl alcohol films cast from aqueous solutions containing inorganic salts. We have established that adding salt leads to an increase in the degree of crystallinity of the polymer. The crystallizing effect of the studied salts increases in the series Na2CO3 = Na2SO4 < NH4Cl < CsCl = NaCl < KCl.
