摘要：

A novel monomer, p-pentamethyldisiloxanyl-alpha,beta,beta-trifluorostyrene, has been synthesized and polymerized to give a white polymer. Membranes obtained from the polymer exhibited an oxygen permeability coefficient (P(O2):cc(STP) cm/cm2s cmHg) and an oxygen separation factor (alpha = P(O2)/P(O2) of 1.8 x 10(-9) and 2.4, respectively. The P(O2) value is considerably higher than values for other poly(mono-substituted tetrafluoroethylenes). The introduction of a pentamethyldisiloxanylphenyl group into poly(tetrafluoroethylene) has been found to be very effective for the enhancement of P(O2) values.
