The density, vapor pressure, surface tension and viscosity of thickened Dowanol, DPM, were measured experimentally according to standard techniques. Each of the techniques is explained in detail and a brief summary of the theory is also presented. A new parameter called the dissolved density was defined which promises to allow differentiation between thickening polymers. The addition of an acrylate polymer had no effect on the surface tension or vapor pressure of the solvent. The effect of thickener concentration on viscosity was determined over a range of shear rates where the thickened solutions were found to follow the power-law fluid model. Author
