The uniaxial extensional flow behavior of polystyrene/low density polyethylene blends (PS/LDPE) was studied using a Rheometrics Extensional Rheometer, Model RER‐9000, at 150°C within the range of the extension rates \documentclass{article}\pagestyle{empty}\begin{document}$ \dot \varepsilon $\end{document} = 0.0005 to 1.0 (s −1 ). The measurements were repeated several times at each deformation rate to ascertain reliability. The effect of the suspending silicone oil was found to be negligible.
