Phase Transitions in Isotactic Polybutene-1

Journal of Macromolecular Science - Physics, 2019
AbstractThe possibilities to influence the 4 major phase transitions of isotactic polybutene – 1 (iPB-1) and their transformation rate are described.

Cohesive zone modelling of fracture in polybutene

Engineering Fracture Mechanics, 2006
Fracture properties of isotactic polybutene-1 have been investigated. Fracture tests have been conducted and relevant properties at initiation have been determined according to linear elastic fracture mechanics. Two distinct fracture mechanisms have been identified, one of them causing partial instability during crack propagation.

Vistanex Polybutene—Rubber Blends

Rubber Chemistry and Technology, 1941
Abstract From the foregoing data on blends of Vistanex Polybutene and rubber, it is evident that these two materials complement one another. Each has properties which the other lacks, and blends of the two can be made to emphasize the more desirable properties of either one.

Composition analysis of polybutenes

Journal of Chromatography A, 1963
Abstract The structure and composition of polyolefins made from pure isobutylene and from isobutylene diluted with various amouts of other light olefins have been investigated. The techniques used were nuclear magnetic resonance and combined anaerobic pyrolysis and gas chromatography.

Peroxidation of polybutene

Die Makromolekulare Chemie, 1963
AbstractThe autocatalytic peroxidation performed dircectly with air of linear polybutene in the absence of special initiators was studied; hydroperoxides, peroxides, “active” hydrogen, alcohols were determined by chemical methods in the oxidized product, and the ketonic carbonyls were determined qualitatively by I.R.

Characterization of polybutenes

Journal of Applied Polymer Science, 1964
To characterize butene polymers, rapid and precise small- and large-scale column fractionation techniques have been developed for low molecular weight pure polyisobutenes and for mixed butene polymers. Fractionation results have been used to determine molecular weight distribution curves of typical commercial butene polymers.

Rubberlike Properties of Polybutene

Rubber Chemistry and Technology, 1940
Abstract Until the last decade the explanation of those properties for which rubber is unique was confined largely to the study of rubber itself. Duplication of these properties involved the synthesis of polymers from isoprene and its immediate homologs.

Peroxidation of isotactic polybutene

Journal of Polymer Science, 1961
AbstractThe reaction of direct peroxidation at 75–90°C. and the simultaneous or successive ones of degradation of the isotactic poly‐α‐olefins are followed through analytical measurements of the total peroxide oxygen content (dialkyl peroxides + alkyl hydroperoxides) and intrinsic viscosity measurements.

Deformation of polybutene‐1 spherulites

Journal of Polymer Science Part A-2: Polymer Physics, 1967
AbstractThe deformation of fresh and aged polybutene‐1 spherulitic samples has been investigated by microscopic observation, interferometry, studying macroscopic and spherulitic birefringence changes, and study of light‐scattering patterns. The spherulite deformation is not affine, the microscopic deformation ratio being less than the macroscopic ...
