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 ...

LDPE and poly(1-butene) blends: Morphology, crystallinity and rheological properties [PDF]

open access: yesPolyolefins Journal, 2021
In this work, the compatibility and crystallinity of low density polyethylene (LDPE) and polybutene-1 (PB-1) blends were studied. Various blends of LDPE/PB-1 containing 5, 10 and 20 wt.% PB-1 were prepared in a corotating twin-screw extruder and ...

Accelerated crystallization and crystal-crystal transition of PB induced by PP with optimized content

open access: yesPolymer Testing, 2023
Isotactic polybutene-1 (PB)/isotactic polypropylene (PP) blends, typical crystalline/crystalline polymer blends with low-melting-temperature (Tm) PB and high-Tm PP, exhibit complicated interactions between their components in both molten and solid states.

Applicazione della meccanica della frattura viscoelastica alla previsione della vita di tubi in polibutene

open access: yesFracture and Structural Integrity, 2013
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
