摘　　要：具有优异物理和化学性能的新聚合物开发推动了取代聚炔的设计与合成。聚炔中功能侧基的引入赋予其非线性光学、液晶、发光、螺旋手性和高气体渗透等性能。作为一种重要的分离膜材料,与传统的玻璃态聚合物膜材料不同,这种无定形、高刚性的聚合物的显著特点是具有非常高的气体渗透系数和蒸汽/气体分离系数。有关其气体分离、天然气净化和对映体拆分等方面的性能已得到深入的研究。本文介绍了取代聚炔的合成用聚合催化剂和聚合物反应及高渗透性聚炔的分离性能。The design and synthesis of substituted polyacetylenes are motivated by the development of new materials that display interesting physical and chemical properties. Attachment of functional pendants to the polyacetylene backbone endows such polymers with various unique properties, such as optical nonlinearity, liquid crystallinity, light emission, helical chirality, high gas permeability, and so forth. As an important category of separation membrane materials, these amorphous, highly stiff, glassy polymers are characterized by high gas permeability and high vapor/gas selectivity, which is strikingly different from conventional glassy polymers. Much work is being progressed in the aspects of gas separation, natural gas purification, and enantloselective permeation of substituted polyacetylenes. This review concerns polymerization catalysts and polymer reaction for the synthesis of substituted polyacetylenes, especially separation properties of the highly permeable polyacetylenes.
