Experimental data of two low-density polyethylene (LDPE) melts at 200°C for both shear flow (transient and steady shear viscosity as well as steady first normal stress coefficient) and elongational flow (transient and steady-state elongational viscosity) were analyzed by use of the Molecular Stress Function (MSF) model.

Pomocí MSF modelu byla analysována experimentální data dvou LDPE tavenin jak pro smykový tak pro elongační tok.
