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 ...

Micro-hardness of surface layer of irradiated Polybutene Terephthalate (PBT)
Using high doses of beta radiation for polybutylene terephthalate (PBT) and its influence on the changes of micromechanical properties of surface layer has not been studied in detail so far. The specimens of PBT were made by injection moulding technology

The Stability of Viscosity of Polybutenes and Polybutene-Mineral Oil Mixtures
In order to obtain the data of the stability of high viscosity standard oils, the variation of viscosity with age was measured by means of a caoillary master viscometer for nolybutenes having viscosities of 55, 340, and 1010 poises at 25°C, and for polybutene-mineral oil mixtures having viscosities of 20, 100, and 540 poises at 25°C.The results ...

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 ...
