Abstract
A capillary rheometer was used to generate data showing the volumetric flow rate at various pressures for a polystyrene resin and for an asbestos filled polystyrene. Variables evaluated were per cent asbestos and temperature. These data were then used to calculate the maximum shear stress at the capillary wall and the corresponding maximum velocity gradient (shear rate) at the capillary wall. A rheological equation containing three constants was employed to relate the shear stress to the shear rate. In addition, a simple relationship was found between the values of two of the constants and the per cent asbestos. There is no apparent relationship between the constants for the unfilled resin and those of the filled resin. However, for the filled resin, the per cent asbestos varies linearly with the log of two of the constants. The filler reduces the effect of temperature and shear stress on the viscosity of the polymer.
