Abstract
Heats of solution of blended and non-blended systems of poly(methyl methacrylate) and poly (vinyl acetate) were measured at 28°C. From the difference between them the heat of blending was estimated according to Hess’s law. The absolute value for the blend prepared by freeze drying, which is thought to be molecularly mixed, was smaller than that for the blend, which shows partial phase separation. This unexpected result is explained by the differences of specific heat behaviour between the systems.
