摘要

The apparent solubility （S）

concentration-average diffusivity （D）

and permeability （P）

for C0

and N

through PPO and aryl-brominated PPO at 35℃for pressure ranging from 1 to 26 atm are reported. It is found that P

and S of the membranes to all the three gases vary with the extent of bromination. S increases with the increase of the percent of bromine in each case

but D to CO

increases remarkably only at higher degree of brominafion

and therefore

P to CO

is increased by more than 100% over a wide range ofpressure in the case. The solubility data are well described by the dual mode sorption model. It is found that the gas molecules sorbed by the Langmuir mode are relatively more immobilized and the contribution of the nonequilibrinm character of the polymer to gas permeation increases obviously for CO

and is hardly changed for CH

with increasing bromine content. These observations are interpreted in terms of changes in specific free volume （SFV）and the cohesive energy density （CED） of the polymers.
