EFFECT OF CHEMICAL STRUCTURE OF SULFOXIDE GRAFTED POLY (VINYL ALCOHOL) ON GAS PERMEABILITY*
摘要:
The effects of chemical structure, i. e. side chain structure and their contents, on thepermeability of pure SO2, N2 and their mixture gases for the sulfoxide grafted poly (vinylalcohol) (RVSO-PVA) membranes have been investigated:where R=Me, Et, Pr, t-Bu and Ph. It was notable that introduction of sulfoxide group intoPVA side chain greatly enhanced the permselectivity of sulfur dioxide. SO2 permeability andseparation factor of these polymers increased markedly as the size of side chain increased. The sulfoxide content of the polymer also played an important role in the pure and mixture gases permeation.Some explanations have been made to interpret this unique gas separation behaviour.
