Interfacial structure and properties of isotactic polybutene-1/polyethylene blends
e-Polymers, 2022 Polymer blending is one of the most economical and effective techniques for achieving products with high comprehensive performances. However, the immiscibility between polymers results in a weak interface, which is typically the position where material ...

Validation of the poke-flow technique combined with simulations of fluid flow for determining viscosities in samples with small volumes and high viscosities [PDF]
Atmospheric Measurement Techniques, 2015 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.

Lamellar thickness and stretching temperature dependency of cavitation in semicrystalline polymers. [PDF]
PLoS ONE, 2014 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
Fluids, 2020 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 ...

Interlocking shish‐kebab morphology in polybutene‐1 [PDF]
Journal of Polymer Science Part B: Polymer Physics, 2002 AbstractThe aim of this research was to explore the effect of shear‐controlled orientation injection molding (SCORIM) on polybutene‐1 (PB‐1). This article describes the methods and processing conditions used for injection molding and discusses the properties of the moldings.

Enhanced Formation of Dicarboxylic Acids in the Catalytic Oxidation of Polyethylene With O2 and NOx
Angewandte Chemie, EarlyView.The oxidation of polyethylene in the presence of a mixture of O2 and NOx and with Cu2+/V5+ as catalyst yields ∼51 mol% diacids, while retaining ∼80 mol% of the carbon in the oil fraction. The developed method is robust and tolerates several polymer types as well as impurities.
