The critical exponent x,, has been examined for some simple, b'iary and ternary fluids using Debye-Chu-Woermann's formula. It is found that xp favours the theoretical prediction of 0.070 by the mode-coupling theory with vertex correction and the calculation of 0.065 by the second-order e-expansion o
## Abstract An engineering equation that describes the steady shear viscosity of polystyrene melts is developed as an extension of the well known power law model for nonβNewtonian viscosity. The parameters in the equation have been related to weight and number averaged molecular weights and tempera
