The shear flow properties of six commercially available long‐chain branching low‐density polyethylene resins were determined, using a cone‐and‐plate rheometer at low shear rates and a capillary rheometer at high shear rates. Also determined were the elongational viscosities of the resins, using an apparatus developed by Ide and White. Interpretation of the rheological measurements is given with the aid of the molecular parameters, namely, molecular weight and molecular weight distribution.
