摘要：

Blends of poly(4-vinylphenol)and a poly(ethylene-co-vinylacetate) copolymer containing 45% by weight of vinyl acetate were studied using infrared spectroscopy. The distribution of hydrogen bonds as a function of temperature and composition was followed by measuring the relative proportions of free and hydrogen-bonded acetate carbonyl groups. These measurements can then be used to map an experimental phase diagram for the system. The phase diagram so obtained is compared to optical microscopy and DSC results and to a theoretically predicted phase diagram based on an association model.
