Breadth in the molecular weight distribution is an inherent feature of synthetic polymer
systems. While in the past this was typically considered as an unavoidable consequence of …

Rheological behavior of polymeric liquids has been considered to be universally determined
by a few time-independent molecular parameters (such as the Rouse relaxation time and …

Poly (butylene terephthalate), polypropylene, and polystyrene nanofibers with average
diameters less than 500nm have been produced by a single orifice melt blowing apparatus …

We provide a Perspective on recent findings in extensional rheology for polymer melts and
solutions with different macromolecular architectures. For linear polymer systems, we focus …

We compare viscoelastic properties of several polystyrene solutions and melts with the
same number of entanglements. It is demonstrated that the modulus and time can be shifted …

In the melt state at equilibrium, entangled nonconcatenated ring macromolecules adapt
more compact conformations compared to their linear analogs and do not form an …

Well-entangled monodisperse linear polystyrene melts exhibit monotonic thinning of the
steady state elongational viscosity with increasing the strain rate ε̇ even beyond the Rouse …

We review constitutive modeling of solutions and melts of linear polymers, focusing on
changes in rheological behavior in shear and extensional flow as the concentration …

Cellulose derivatives containing associating hydrophobic groups along their hydrophilic
backbone are used as rheology modifiers in the formulation of water-based spray paints …

Nonlinear extensional flows are common in polymer processing, but they remain
challenging theoretically because dramatic stretching of chains deforms the entanglement …
