研究了由聚[1-（三甲基硅基）-1-丙炔]、聚（叔丁基乙炔）和聚（1-氯-2-苯乙炔）制备的三种聚乙炔膜的气体渗透性能。尽管取决于聚合和膜制备的条件，但聚合物在25°C下对氧和氮的典型渗透系数P如下：（三甲基硅烷基）-1-丙炔]，PO 2 = 40 × 10−8，PNr 2 = 20 × 10−8;聚（叔丁基乙炔），PO 2 = 3.0 × 10−8，PN 2 =1.0×10−8;聚（1-氯-2-苯乙炔），PO 2 = 9.4 × 10−10，PN 2 =2.0×10− 10 cm 3（STP）· cm/（cm 2· s · cm Hg）。因此，聚[1-（三甲基甲硅烷基）-1-丙炔]膜的PO 2是已知膜中最大的，并且聚（叔丁基乙炔）和聚（1-氯-2-苯乙炔）膜的值也相当大。研究了聚合物结构、测量温度等因素对聚乙炔薄膜的PO 2和PN 2的影响。讨论了这些薄膜应用于空气富氧的可能性。
The gas permeabilities of three polyacetylene films, prepared from poly[1‐(trimethylsilyl)‐1‐propyne], poly(tert‐butylacetylene), and poly(1‐chloro‐2‐phenylacetylene), were studied. Although depending on conditions of polymerization and membrane preparation, typical permeability coefficientsPof the polymers to oxygen and nitrogen at 25°C were as follows: poly[1‐(trimethylsilyl)‐1‐propyne],PO2= 40 × 10−8,PNr2= 20 × 10−8; poly(tert‐butylacetylene),PO2= 3.0 × 10−8,PN2=1.0×10−8; poly(1‐chloro‐2‐phenylacetylene),PO2= 9.4 × 10−10,PN2=2.0×10−10cm3(STP) · cm/(cm2· s · cm Hg). ThusPO2of a poly[1‐(trimethylsilyl)‐1‐propyne] film is the largest among those ever known, and the values of poly(tert‐butylacetylene) and poly(1‐chloro‐2‐phenylacetylene) films are also fairly large. Influences of polymer structure, measuring temperature, and so forth on thePO2andPN2of these polyacetylene films were studied. The possibility of applying these films to oxygen enrichment of air are being discussed.
