The rheological behavior of blend, e.g. polypropylene,PP, with polyamide - 6, PA6, has been investigated.Results show that this blend is a pseudo plastic fluid and the amount of PA6 seems to be a dominator to influence all rheological properties. In addition to the expected influence by temperature generally for polymer, it has been found the amount of PA6 is valid in a range, e.g. 0-20% corresponding to the PP amount, i.e. in this range, the larger the PA6 added, the larger is the nonNewtonian index, n, and this is obviously especially for PP/PA6 blend with the high shear stress.
