A novel monomer, p-pentamethyldisiloxanyl-α,β,β-trifluorostyrene, has been synthesized and polymerized to give a white polymer.Membranes obtained from the polymer exhibited an oxygen permeability coefficient (PO2: cc(STP) cm/cm2scmHg) and an oxygen separation factor (α=PO2/PO2) of 1.8 * 10-9 amd 2.4, respectively.The PO2 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 the enhancement of PO2 values.
