Apparent viscosities of linear polyethylene melts may be simply related to molecular weight at various shear stresses. One gets constant slopes on a log–log scale with higher critical M̄ w at higher shear stresses. The validity of Ferry's equation and the dependence of its coefficients are extensively analyzed.
