Flow-induced crystallization (FIC) is a typical nonequilibrium phase transition and a core
industry subject for the largest group of commercially useful polymeric materials …

Polymer extrudate swell is a rheological phenomenon taking place after polymer melt flow
emerges the die exit of extrusion equipment, due to flow redistributions and molecular stress …

Although 3D printing has the potential to transform manufacturing processes, the strength of
printed parts often does not rival that of traditionally-manufactured parts. The fused-filament …

Three-dimensional (3D) printing is rapidly becoming an effective means of prototyping and
creating custom consumer goods. The most common method for printing a polymer melt is …

Semi-crystalline polymers containing amorphous and crystalline regions usually have
intimately mixed chains. The resulting topological constraints (entanglements) in the …

We propose a theoretical framework for dealing with a transient polymer network
undergoing small deformations, based on the rate of breaking and reforming of network …

Recently we developed a theory for fast flows of entangled polymer melts which includes the
processes of reptation, convective and reptation-driven constraint release, chain stretch and …

We investigate the nonlinear shear and uniaxial extensional rheology of entangled
polystyrene (PS) melts and solutions having the same number Z of entanglements, hence …

Achieving better control in fused filament fabrication (FFF) relies on a molecular
understanding of how thermoplastic printing materials behave during the printing process …

Existing methods to obtain the primitive path network for monodisperse, linear polymers in
the molten state are critically compared. A connection is established between the original …
