摘要：

Both the oxygen permeability coefficient (P(o)2) and the separation factor (alpha = P(o)2/P(N)2) of polydimethylsiloxane and poly(1-trimethylsilylpropyne) films were enhanced by adding a small amount (1.0 wt.%) of poly(trifluoromethyl substituted arylacetylene). These enhancements were caused by the selective dissolution of oxygen at the surface of the blend films, which was considered to be effected by the poly(trifluoromethyl substituted arylacetylene).
