Statistical analysis of inherent viscosities (LVN), shear modulus (G*), and melting temperature (Tm) interval data for isotactic polypropylene–linear polyethylene (HDPE) blends was performed in order to verify their microheterogeneity. High shear measurements in viscometric (Poiseuille's) flow were carried out on four replicated compositions of the blends. Least-squares treatment of the results yielded power law parameters for the blends differing in composition. The significance of differences between the blends of various HDPE content was tested using the multiple-range (Duncan's) test, and tentative conclusions are drawn on the composition dependence of the melt flow viscosities of the blends.
