✦ Synopsis

Lowdensity polyethylene film was subjected to direct fluorination on one surface by exposure to a dilute fluorine gas stream for various periods of time. Various analyses indicate partial fluorination of a thin surface layer. The permeability coefficients for He, COz, and CH4 were measured at 35T. The permeability of He was not changed by fluorination; whereas, values for COz and CHI were decreased by as much as two orders of magnitude. The selectivity of transport for gas pairs of different molecular size was greatly improved, suggesting applications of this technique for membrane separation processes.

## Abstract High density polyethylene was biaxially oriented by high‐pressure forging and subsequently low‐pressure thermal forming. The permeability of O~2~, CO~2~, and CH~4~ was reduced slightly by biaxial orientation, the diffusivity of the gases was found to increase with the degree of orientat
