Thermal conductivity and heat capacity per unit volume of poly(methyl methacrylate) under high pressure

• The thermal conductivity and heat capacity per unit volume of poly(methyl methacrylate) (25 and 350 kg · mol−1 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 value g = 3.4 ± 0.3 for the Bridgman parameter. No dependence on molecular weight could be detected in the properties we measured.
