As can be seen, the [[theta].sub.combined] values are below zero, which means that the pressure effect predominates over the dissipation effect, under the shear rates of 1 x [10.sup.3] - 1 x [10.sup.5], 1 x [10.sup.3] - 6 x [10.sup.5], and 1 x [10.sup.3] - 3 x [10.sup.5] [s.sup.-1] for the PS, PP, and LLDPE melts, respectively.
