N2 - The pure gas solubility and permeability of H2, O2, N2, CO2, CH4, C2H6, C2H8, CF4, C2F6 and C3F8 in poly(1-trimethylsilyl-1-propyne) were determined as a function of pressure at 35 °C. The permeability coefficients of the perfluorinated penetrants were approximately an order of magnitude lower than those of their hydrocarbon analogs, and lower even than those of the permanent gases. In striking contrast to hydrocarbon penetrants, the permeability of the polymer to fluorocarbon penetrants decreased with increasing penetrant size.
