Interfacial structure and properties of isotactic polybutene-1/polyethylene blends

open access: yese-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]

open access: yesAtmospheric 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.

Crystallization of Polymers from Solution under ShearingStress III Polybutene-1 [PDF]

open access: yes, 1968
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 ...

An improved method for the high isotacticity measurement of polybutene-1

open access: yesPolymer Testing, 2021
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 ...

Interfacial nucleation in iPP/PB-1 blends promotes the formation of polybutene-1 trigonal crystals [PDF]

open access: yes, 2018
The formation of trigonal Form I\ub4 crystals of polybutene-1 (PB-1) directly from melt has drawn much attention in past decades. In this study, we investigate the fractionated crystallization behavior of PB-1 within droplets formed by blending PB-1 with
