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.

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.

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.
