    Notes: Abstract The transitions to the glassy state in viscous crude oils have been investigated at high pressures by the transient hot-wire method, by differential scanning calorimetry, and by equation-of-state measurements. The range of pressures investigated was up to 1.2 GPa in the temperature interval 150–370 K. The glass transition in crude oils is a common phenomenon and occurs due to the viscosity increase on decreasing the temperature or increasing thepressure. The actual transition coordinates depend not only on physical properties but also on the characteristic experimental time.

    Thermal conductivity and heat capacity per unit volume of poly(methyl methacrylate) under high pressure (1994)
    Springer
    International journal of thermophysics 15 (1994), S. 949-962

    Topics: Physics
    Notes: Abstract The thermal conductivity and heat capacity per unit volume of poly(methyl methacrylate) (25 and 350 kg · mol− in molecular weight) have been measured in the temperature range 155–358 K at pressures up to 2 GPa using the transient hot-wire method. The bulk modulus has been measured up to 1.0 GPa at 294 K and yielded a constant valueg = 3.4 ± 0.3 for the Bridgman parameter. No dependence on molecular weight could be detected in the properties we measured.
