The ultrasonic velocity and density of liquid mixtures of water and poly(ethylene glycol)-200 have been measured at 30°C. The variation of sound velocity and adiabatic compressibility with concentration shows a change in the slope at a mole ratio of four indicating the formation of tetrahydrate.

The interaction of water with poly(ethylene glycols) has been studied by measuring the density of aqueous solutions of a series of poly(ethylene glycols) (PEGs) ranging in number average molecular weights from 106 to 5607. In all cases except that of diethylene glycol the slope of the density/compos
## Abstract The unperturbed molecular dimensions of poly(ethylene glycol) (PEG) samples (of different molecular weights) have been evaluated in aqueous solutions from viscosity measurements at 25, 30, 35, and 40°C. The unperturbed dimension, __K__~θ~, has been determined from extrapolation methods,
