Precision measurements of osmotic pressure have been carried out with several polymers (dextran, hydroxyethyl cellulose, polyvinylpyrrolidone and polyethlene oxide) in aqueous solutions. The concentration dependence of the osmotic pressure over a wide range of concentrations (up to 0-2 g/cm 3) was e

Concentrated solutions of poly(vinyl acetate)/toluene and poly(dimethyl siloxane)/octane were investigated in the polymer volume fraction range 0.08 ~ ¢ ~< 0.5 using small angle X-ray scattering. As the concentration increases the polymer-polymer correlation length deviates increasingly from the pre

## Abstract We propose simple expressions $\Pi /\Pi \_0 = 1 + (\varphi /\varphi \_{{\rm ex}} )^{3\alpha - 1}$ and $(\delta \_0 /\delta )^2 = 1 + (\varphi /\varphi \_{{\rm ex}} )^{2\alpha }$ for the osmotic pressure Π and the depletion thickness __δ__ as a function of the polymer concentration __φ__
