Applicazione della meccanica della frattura viscoelastica alla previsione della vita di tubi in polibutene [PDF]
, 2007 Il Polibutene-1 isotattico (i-PB1) è un materiale polimerico usato per la produzione di tubi per il trasporto di fluidi in pressione. In questo lavoro si sono studiati due tipi di i-PB1 prodotti da Basellche differiscono per grado di isotatticità.Si sono

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.

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