Glass-Transition-Temperature-Independent Form II to I Phase Transition of Low-Molar-Mass Isotactic Polybutene-1

, 2021
Temperature-dependent form II to I transition in isothermally crystallized low-molar-mass polybutene-1 has been investigated by means of fast scanning calorimetry.

Crystallization and Transformation of Polybutene‐1

Journal of Macromolecular Science, Part B, 2004
Abstract The isothermal crystallization and phase II → I transformation of bulk polybutene‐1 at various temperatures have been characterized by x‐ray diffraction. The crystallization rate can be increased or decreased by the addition of various solids, with sodium salicylate and talc, e.g., increasing the rate by >100% and, unexpectedly, decreasing the

Nucleation Mechanism for Form II to I Polymorphic Transformation in Polybutene-1

Macromolecules, 2020
By means of in situ small-/wide-angle X-ray scattering (SAXS/WAXS) techniques, nucleation mechanism for Form I crystals of polybutene-1 (PB-1) has been investigated by heating the early-stage polym...

Polybutenes in Orchard Pest Control

The Canadian Entomologist, 1962
In British Columbia the control of phytophagous mites, especially the European red mite, Panonychus ulmi (Koch), and the McDaniel spider mite, Tetranychus mcdanieli McG., is becoming increasingly difficult, mainly because of the mites' ability to develop resistance to most acaricides in a relatively short time (3).

Growth morphology of isotactic polybutene-1

European Polymer Journal, 1973
Abstract Isotactic polybutene-1 has been crystallized from solution by the film formation method. Well-defined single crystals have been grown from solutions of the polymer in amyl acetate and its mixtures with n-butanol in all the three modifications by varying the concentration and crystallization temperature.

Spherulite deformation in polybutene‐1

Journal of Polymer Science Part B: Polymer Letters, 1963
Abstract : The postulate of spherulite deformation has now been verified by direct microscopic observation. Films of polybutene-1, about 1 mil thickness, (made from samples obtained through the courtesy of Phillips Petroleum Company) were prepared by molding in a laboratory press at 150 C for 15 min at 2,000 psi pressure and then lowering the ...

Effect of polymorphism of isotactic polybutene‐1 on peel behavior of polyethylene/polybutene‐1 peel systems

Journal of Applied Polymer Science, 2007
AbstractThe effect of polymorphism of isotactic polybutene‐1 (iPB‐1) on the peel behavior of the specific peel system low‐density polyethylene/polybutene‐1 (LDPE/iPB‐1) was investigated using wide‐angle X‐ray scattering, calorimetry, and the T‐peel test.
