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/cm2 s cmHg) and an oxygen separation factor (αPo2/Po2) of 1.8×10−9 and 2.4, respectively. The Po2 value is considerably higher than values for other poly(mono-substituted tetrafluoroethylenes)
已经合成并聚合了新型单体,对-五甲基二硅氧烷基-α,β,β-三氟苯乙烯,得到白色聚合物。从聚合物得到的膜显示的氧渗透系数(P ø 2:CC(STP)厘米/厘米2小号厘米汞柱)和氧分离因子(α P O2 / P O2)的1.8×10 -9和2.4,分别。的P Ô 2值大于其它的聚(单取代的四氟乙烯)值要高得多。已经发现将五甲基二硅氧烷基苯基引入聚四氟乙烯对于提高P非常有效。o 2个值
