Abstract
High density polyethylene compositions having a high flow index and a bimodal composition provides an outstanding combination of processability, stiffness and ductility in rotomolded articles. The compositions have a low relative elasticity (G'/G″, measured at 0.05 rad/sec) of less than 0.03.
