ilicon-containing polyimide with biphenylene moiety in polymer backbone was prepared in our laboratory.Temperature dependence of gas pairs(H2/N2 and O2/N2)of this polymer was discussed. The permeability and diffusivity increased with the rise of temperature
whereas the solubilty and permselectivity decreased. Furthermore
the activation energy for gas permeation and diffusion and heat of sorption were also reported.
