Abstract

Polystyrenes with structurally different oligosiloxanes as p-substituents were synthesized and the selective oxygen permeation through the polymer film was studied. It was found that the structure of the p-oligosiloxane substituents had great effects not only on the glass transition temperature of the polymer but also on the oxygen permeation behavior through the polymer film. Trimethylsiloxyl groups, especially, were shown to play an essential role in enhancing the permeability.
