A New Look at Extensional Rheology of Low-Density Polyethylene

The nonlinear rheology of three selected commercial low-density polyethylenes (LDPE) is measured in uniaxial extensional flow. The measurements

Stress Relaxation of Bi-Disperse Polystyrene Melts: Exploring the Interactions between Long and Short Chains in Non-Linear Rheology

We present start-up of uniaxial extension followed by stress relaxation experiments of a bi-disperse 50 % by weight

The effect of network topology on material properties in vinyl-ester/styrene thermoset polymers using molecular dynamics simulations and time–temperature superposition

The time–temperature superposition principle (TTSP) is a promising tool for filling the time-scale gap between molecular dynamics simulation
