Abstract

In this work rheological behavior of POLYETHYLENE/polypropylene BLENDs produced by Arak and Bandar Imam Petrochemical complexes was investigated. The VISCOSITY of homopolymers, PE and PP, and their BLENDs at different concentration proportions were measured. The measurements have been carried out by using a capillary rheometer. The results for the BLENDs show that when two homopolymers with great difference in shear VISCOSITY form a BLEND, the VISCOSITY of the BLENDs are intermediate between the VISCOSITY of homopolymers. On the other hand, for the two homopolymers (PE and PP) with viscosities close to each other, the curve of viscous homopolymer falls down quickly below the VISCOSITY of BLENDs with high shear rate. It has been shown that the VISCOSITY of the BLENDs versus PE content has negative deviation from logarithmic addition rule. The modeling of VISCOSITY of BLENDs in respect to concentration of homopolymers has been produced and it is shown that the modified Kulezner model can predict the VISCOSITY of the BLENDs in terms of viscosities of original resins with very good precision.
