Mpemba Effect in Crystallization of Polybutene-1 [PDF]
The Mpemba effect and its inverse can be understood as a result of nonequilibrium thermodynamics. In polymers, changes of state are generally non-equilibrium processes.

Applicazione della meccanica della frattura viscoelastica alla previsione della vita di tubi in polibutene [PDF]
Isotactic polybutene-1 (i-PB1) is a polymer used for the manufacturing of pressurized pipes. In this work two grades of i-PB1 with a different degree of isotacticity have been investigated; they have been supplied by Basell Polyolefins. Fracture tests

Computational Predictions for Boger Fluids and Circular Contraction Flow under Various Aspect Ratios [PDF]
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 ...

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 ...

Cross-Nucleation between Polymorphs: Quantitative Modeling of Kinetics and Morphology. [PDF]
Cross-nucleation is defined as the nucleation of one polymorph on the surface of another polymorph of the same substance. Although the description of this particular form of heterogeneous nucleation is mainly phenomenological, recently dedicated ...
