Unique Shear Flow Rheological Characterization of Nylon 6 and Its Nylon 610-Based Blends

Abstract

Unique observations on the shear flow rheological characterization of nylon resins, especially in the high-shear-rate region, nylon 6 and its nylon 610 blends in particular, are reported. The main aims of our study were to deal with a deviation of nylon melt from the Ostwald-de Wale equation, well accepted for polymers to date. It was found that rheological data of nylons fit well with the logarithmic law. Such unique results, in contrast to those for polyethylene and polypropylene, were tentatively attributed to the rupture of H-bonding in nylon melts.
