Abstract
The large amplitude oscillatory shear test has been used to discrimina te subtle differences in nonlinear viscoelasticity between two high de nsity polyethyene blow molding resins with different processability. S tructural network theory was used to explain the subtle differences in terms of entanglement kinetics with remarkable accuracy. The resin wi th better shape retention characteristics in programmed parison blow m olding was found to have a higher kinetic rate constant for molecular re-entanglement.
