摘要：

Effects of aryl-halogenation on the permeability of poly(phenolphthalein terephthalate) and poly(bisphenol A phthalate) to several permanent gases are reported. Analyses based on separate solubility and diffusivity considerations are presented. The influence of reduced packing density of the polymer on the equilibrium gas sorption capacity and steady-state gas-permeability of the polymer is addressed. The results concur well with previous findings on poly(2,6-dimethyl phenylene oxide) and its aryl-brominated counterparts. Finally, the relationships among polymer chain rigidity, gas-diffusivity, gas molecular size, and permselectivity of the polymer are analyzed.
