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 (P_O2) with relatively high oxygen permselectivity (α = P_O2/P_N2). In α vs. P_O2 plots, 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.

新颖的四个新的部分修饰的膜（共）具有光分解性主链和交联的侧链的聚乙炔表现出优异的性能如氧选择性渗透膜，即，超高氧气渗透率（P _{Ò 2}）具有相对高的氧渗透选择性（α=  P _{Ô 2} / P _{N 2}）。在αvs. P _{O 2中} 图中，其中两个显示的性能接近于Robeson的上限2008，另外两个超过了Robeson的上限1991。（共）聚合物的刚性主链，超分子聚合物的规则结构和柔性交联的组合结构可能产生了这些出色的性能。
