Sorption of phenyl benzoate by polyethylene: Nature and stability of the sorption centres

Abstract

The sorption of phenyl benzoate vapours by high density polyethylene has been studied. The sorption isotherms are described by the Langmuir law, the sorption limit remaining constant in the interval 70-180°C and not changing on melting of the polymer. This points to the topological nature of the centres sorbing the low-molecular weight substances dissolved in the polymer. © 1988.
