Abstract
A range of measurements are reported on a series of substituted cyclic carbonates and α,β-unsaturated aldehydes. The properties studied include the zero shear viscosity, thermal pressure coefficient, adiabatic compressibility, specific heat at constant pressure and the density. Certain of the liquids studied show a marked tendency to supercool and to exhibit pre-freezing phenomena. The magnitude and temperature dependence of the properties studied are discussed in terms of cluster formation occurring above the melting point. The source of the molecular interactions responsible for the cluster formation is discussed.Keywords
