四种新型的具有光降解主链和可交联侧链的新型（共）聚乙炔的部分改性膜表现出优异的氧选择透过性膜性能，即具有较高的氧选择透过性（α = PO 2/PN 2）和较低的氧透过率（PO 2）。在α vs.PO2图中，其中两个显示出接近Robeson上限2008的性能，另外两个超过Robeson上限1991。这些优异的性能可能是由于聚合物主链的刚性、超分子聚合物的规则结构和柔性交联结构的结合。
Four new partly modified membranes of novel (co)polyacetylenes having a photodegradative backbone and crosslinkable side chains showed excellent performances as oxygen permselective membranes, that is, ultrahigh oxygen permeability (PO2) with relatively high oxygen permselectivity (α =PO2/PN2). In α vs.PO2plots, two of them showed a performance close to Robeson's upper bound 2008 and the other two exceeded Robeson's upper bound 1991. The combination of the rigid main chain of the (co)polymers, the regular structure of the supramolecular polymer, and the flexible crosslinking structure may have produced these excellent performances.
