Popis: The temperature dependences of the heat content (Cp=ƒ(T)) of polyvinyltrimethylsilane (PVTMS) binary blends with cyclohexane or heptane have been studied in an adiabatic vacuum calorimeter in the 80–300°K range. The Cp=ƒ(T) diagrams showed glass transition of the cyclohexane or heptane solutions in the PVTMS and also crystallization, the solid-state transitions of the cyclohexane and heptane, and their melting when their contents in the blends with PVTMS exceeded solubility. The physical state diagrams were plotted for the above blends and allowed the determination of the number of such states, especially of the phases and of their physico-chemical nature as a function of the total mixture composition over a wide range of temperature.
