Polymers with oligoorganosiloxane side chains as material for oxygen permeable membranes

Abstract

Styrene and methacrylate type monomers having oligoorganosiloxane substituents were synthesized, and the properties of the polymers therefrom as material for oxygen permeable membranes were evaluated by gas chromatographic method. Homopolymers with short siloxane chains were found to be better than those with long branches in selectivity in permeation and mechanical strength. Introduction of fluorine atoms into polymer structuredid not improve the selectivity in permeation. © 1985 The Society of Polymer Science, Japan.
