Many flow phenomena in a capillary are believed to be rooted in the slip occurring between the molten polymer and wall surface. Despite increasing industrial applications of bimodal molecular weight distribution (MWD) polyethylene, their slip behaviour has not been fully understood. Slip studies in simple shear were conducted on metallocene-based bimodal MWD polyethylene resins. Shear stress values in the absence of slip were measured using a stress-control rotatory rheometer by conducting small amplitude oscillatory shear (SAOS) tests at 190 °C in the frequency range of 0.01-500 rad/s and assuming Cox-Merz relationship. A sliding plate rheometer (SPR) was used to measure shear stress in the presence of slip. The SPR tests were conducted at 190 °C at different shear rates. Data obtained from these two experiments are used to derive slip velocity versus shear stress curves. Slip velocities of resins with different molecular weight distribution are compared.
