摘要：

The rheological and morphological behaviors of three binary blends of polyethylenes regarding the melt index and density. one component made by Ziegler-Natta and the other by metallocene catalysts. have been investigated to elucidate miscibility and phase behavior. If the comonomer contents are similar, then the melt viscosity is weight average value, otherwise it shows different behavior: the FA+FM blend is miscible. but the RF+EN and RF+PL blends inform immiscible. The microtomed cutting surface indicates that all the blends are not homogenous regardless the density, melt index and cooling processes, and show banded spherulites.
