Polystyrenes with p-oligo-siloxane,silane, germanosiloxane,germane, or stannane as p-substituents as materials for oxygen permeable membranes

The title polymers were synthesized and the oxygen permeation behavior through the polymer films were studied. The oligodimethylsilane-substituted polystyrenes showed a little low Po₂ compared with the oligodimethylsiloxane-substituted polystyrenes. The important role of trimethylsiloxyl group in permeation was suggested.
