Strain hardening of polymer melts is able to improve the uniformity of items in processing
operations with elongational deformation. Of particular interest in this aspect is the …

The basics of the uniaxial stretching of polymer melts and solutions are considered,
including analysis of the transient regimes of deformation, as well as the different types of …

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 …

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 …

The shear and elongational rheology of linear and pom-pom shaped polystyrene (PS)
blends was investigated experimentally and modeled using constitutive models such as the …

The elongational rheology of blends of a polystyrene (PS) Pom-Pom with two linear
polystyrenes was recently reported by Hirschberg et al.(J. Rheol. 2023, 67: 403–415). The …

Bottlebrush polymers are combs with extremely high grafting density along their backbone
chain. We consider the rheology of bottlebrush poly (α-olefins) with side chains ranging from …

This work studies the origin of the so called" strain hardening" observed when comparing
the transient stress response of entangled melts to uniaxial extension with that to simple …

For processing operations with a pronounced elongational component, it was found that the
uniformity of extruded items is improved by the presence of strain hardening usually …

Reactive extrusion with pyromellitic dianhydride (PMDA) and tetraglycidyl diamino diphenyl
methane (TGDDM) was conducted to create long-chain branched poly (ethylene …
