Sorption Characteristics of Binary Hydrocarbon Mixtures in Low Density Polyethylene

Abstract

Sorptions of six pure hydrocarbons and five of their binary mixtures in low density polyethylene have been measured. Composition of the binary mixture sorbed has been determined experimentally by a direct method. Selectivity uue to sorption has been shown to constitute a major portion of the permselectivity. Correlations have been developed to predict the quantity and composition of the binary mixture sorbed in the polymer at any temperature, when the pure compound sorptions at some temperature are known
