Volumetric data on the supercooled liquid state and on the glassy state are reported for a binary mixture of triphenylchloromethane and o-terphenyl. In the supercooled liquid state, the thermal expansivity, the isothermal compressibility, and their temperature dependences of the mixture are much samller than those of simple molecular liquids and are almost the same order of magnitude as those of polymer liquids. The glass of the mixture also closely resembles polymer glasses in the apparent thermodynamic properties. Some representative lattice-like liquid theories are applied to the pressure-volume-temperature relations of the supercooled liquid sample, with the aid of the principle of corresponding states.
