An improved method for the high isotacticity measurement of polybutene-1
High isotactic polybutene-1 (HiPB) plays important roles in presenting outstanding resistance to creep and crack at high temperature. Therefore, rapid and accurate measurement of the HiPB is extremely important for both synthesis and application of ...

Validation of the poke-flow technique combined with simulations of fluid flow for determining viscosities in samples with small volumes and high viscosities [PDF]
Viscosity in particles consisting of secondary organic material (SOM) has recently become an area of research focus, since information on viscosity is needed to predict the environmental impacts of SOM particles. Recently Renbaum-Wolff et al.

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 ...

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 ...

How entanglements determine the morphology of semicrystalline polymers [PDF]
Crystallization of polymers from entangled melts generally leads to the formation of semicrystalline materials with a nanoscopic morphology consisting of stacks of alternating crystalline and amorphous layers. The factors controlling the thickness of the

Low-temperature rheology and thermoanalytical investigation of lubricating oils: Comparison of phase transition, viscosity, and pour point [PDF]
According to the ASTM D97, the pour point is the temperature below which petroleum products cease to flow. To evaluate the relevance of pour point measurements for synthetic lubricating oils, we investigated the crystallization, melting temperature and ...

Protein adsorption on nanostructured polymer surfaces [PDF]
Human plasma fibrinogen (HPF) plays an essential role in the initial host response to biomaterials. Developing strategies for controlling the HPF biomaterial interactions is crucial but is still in its infancy.
