## 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 Ξ  and the depletion thickness __Ξ΄__ as a function of the polymer concentration __Ο†__

## Abstract In a plasticating extruder, solid polymers are heated and are subjected to high pressures before they are melted and delivered to a die. In both the solids conveying and melting sections, these temperature and pressure increases will compact the unmelted polymer bed as it moves down the
