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 …

Over the past 25 years, IRIS has become an integral resource in materials laboratories
around the world, bringing together stimulating communities of rheology experimentalists …

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 …

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 …

A large number of well-equilibrated atomistic configurations of linear, strictly monodisperse
polyethylene (PE) melts of molecular length ranging from C24 up to C1000, obtained …

We report on recent progress in our understanding of the rheological behavior of polymer
melts, resulting from the work of several investigators, mostly on fast extensional flows. They …

The start-up and steady uniaxial elongational viscosity have been measured for two
monodisperse polystyrene melts with molecular weights of 52 and 103 kg∕ mole, and for …

To optimize automation for polymer processing, attempts have been made to simulate the
flow of entangled polymers. In industry, fluid dynamics simulations with phenomenological …

Reactive processing on conventional poly (ethylene terephthalate)(PET) with the
combination of pyromellitic dianhydride (PMDA) and triglycidyl isocyanurate (TGIC) was …

The study of commercial low-density polyethylenes (LDPEs) has always focused on the
effects of the molecular architecture of the polymer on its shear and extensional rheological …
