Crystallization of Polymers from Solution under ShearingStress III Polybutene-1 [PDF]
It was shown that the fibrous crystals of isotactic polybutene-l crystallized from solution under shearing stress are also composed of the central threads with an extended chain character and the epitaxally deposited lamellae with a folded chain ...

The influence of branching efficiency on the rheology and morphology of melt state long chain branched polypropylene/polybutene-1 blends [PDF]
In this study, the compatibility of the blends of polypropylene (PP) and polybutene-1(PB-1) homopolymer before and after long chain branching process were studied.

A robust method for calculating interface curvature and normal vectors using an extracted local level set [PDF]
The level-set method is a popular interface tracking method in two-phase flow simulations. An often-cited reason for using it is that the method naturally handles topological changes in the interface, e.g.

Lamellar thickness and stretching temperature dependency of cavitation in semicrystalline polymers. [PDF]
Polybutene-1 (PB-1), a typical semicrystalline polymer, in its stable form I shows a peculiar temperature dependent strain-whitening behavior when being stretched at temperatures in between room temperature and melting temperature of the crystallites ...

Computational Predictions for Boger Fluids and Circular Contraction Flow under Various Aspect Ratios
This work puts forward a modeling study contrasted against experimental, with focus on abrupt circular contraction flow of two highly-elastic constant shear-viscosity Boger fluids, i.e., a polyacrylamide dissolved in corn-syrup PAA/CS (Fluid-1) and a ...

Polymorphism and crystal transition are common phenomena of semicrystalline polymers. These two behaviors are known to be controlled by the nucleation and chain mobility of polymers, both of which are constrained by the chain entanglement at the ...

Particles adsorbed at various non-aqueous liquid-liquid interfaces [PDF]
Particles adsorbed at liquid interfaces are commonly used to stabilise water-oil Pickering emulsions and water-air foams. The fundamental understanding of the physics of particles adsorbed at water-air and water-oil interfaces is improving significantly ...

On the Influence of Concentration on the Rheology of Polymer Solutions: Can Scaling Laws Be Found?
The present work is concerned with the study of the rheology of polymer solutions spanning different concentration regimes and originates from a former round-robin research programme on this subject, the S1 project, involving a number of research groups ...
