Styrene-butadiene-styrene modified binders (SBS-MBs) exhibit significant property deterioration during storage at elevated temperatures (≥180 °C) in closed containers due to the degradation of the SBS molecules. This study examines the effect of w

The upper service temperature rheological properties of styrene-butadiene (SB) polymer modified binders (PMBs) were analyzed as a function of the molecular structure (linear triblock, high vinyl triblock, branched triblock, and linear diblock SB poly

Recent shear experiments in well-entangled polymer solutions demonstrated that interfacial wall slip is the only source of shear rate loss and there is no evidence of shear banding in the micron scale gap. In this work, we experimentally elucidate ho

In geometries capable of producing uniform shear stress across the gap such as cone–plate, it is a challenge to study the nonlinear rheology of well-entangled polymers without wall slip and edge fracture. The task to obtain meaningful steady-state

The recent particle-tracking velocimetric (PTV) observations revealed that well-entangled polymer solutions and melts tend to either exhibit wall slip or assume an inhomogeneous state of deformation and flow during nonlinear rheological measurements
