Abstract
Differential calorimetry has been employed in two different instrumental modes to measure ice nucleation rates in undercooled water and aqueous solutions of polyethylene glycol (PEG) as a function of temperature. The results are consistent with the classical theory of homogeneous nucleation kinetics. It appears that the inhibition of ice nucleation by PEG results mainly from a marked perturbation of the diffusional freedom of water molecules by the polymer.
