Polymer mixtures of poly(vinyl nitrate) (PVONO2), and poly(vinyl acetate) (PVOAc), which had previously been concluded to be compatible with each other, were investigated by the dilatometric method. As a result, a characteristic behavior of the mixtures was observed. Each mixture showed a single glass-transition temperature (Tg) over the whole range of composition; this temperature was higher than those of pure polymers in the middle region of composition. The transition temperatures of the mixtures obeyed a modified Gordon-Taylor expression. The thermal expansion coefficients of the mixtures are discussed in relation to the effect of blending.
