摘要：

The i.r. spectra and the melting behaviour of blends of poly(vinyl alcohol) (PVAl) and poly(acrylic acid) (PAA) have been studied as a function of blend composition. Replacement of H-bonding interactions in pure PAA and PVAl by intermolecular interactions has been proved by analysis of the OH and C=O stretching region in the i.r. spectra. The efficiency of these intermolecular interactions results in a rapid decrease of the crystallinity of PVAl when the PAA content increases and its complete supression when the PAA content equals or exceeds 50 wt%. A very high negative value has been obtained for the interaction parameter by measurement of the melting point depression.
