Thermodynamic properties of polybutene‐1 and butene‐1

Journal of Polymer Science Part A-2: Polymer Physics, 1967
Abstract : Using published specific heat data, the entropy, enthalpy, and Gibbs free energy of polybutene-1 (PB) were calculated over the temperature range 0 to 315K. The encraty, C sub p/T vs. T, calculated for PB exhibits a maximum at 60K and a small inflection at about 250K, which is associated with the glass transition.

Crystallization studies on deformed polybutene‐1 melts

Polymer Engineering & Science, 1971
AbstractAn apparatus was designed and built which allowed an investigation concerning the morphology and kinetics of crystallization of a deformed polybutene‐1 melt. The polymer was quenched from a temperature above its melting point to one of two crystallization temperatures.

Dilute solution properties of isotactic polybutene-1

European Polymer Journal, 1969
Abstract Viscosity measurements have been made on fractions of a highly isotactic polybutene-1 sample in cyclohexane and its mixtures with the poor solvent n -propanol at various temperatures. Light scattering measurements were made in cyclohexane at 35°.

Isotactic polybutene‐1: Internal pressure measurements

Die Makromolekulare Chemie, 1969
AbstractSome internal pressure (Pi) measurements on modification 1 and 2 of isotactic polybutene‐1 are reported.They confirm the solid‐solid transition at 65°C for form 2 and show Pi of 1, at room temperature, to be higher than that of both form 2 and the melt; the molten polymer has an internal pressure intermediate between form 1 and form 2.
