本文综述了近年来取代乙炔聚合的研究进展，重点介绍了聚二苯乙炔的合成和苯乙炔的活性聚合。二苯基乙炔（DPA）与TaCl 3-n-Bu 4Sn聚合得到热稳定性很好但不溶于任何溶剂的聚合物。具有各种基团的DPA（例如，p-Me 3Si、m-Me 3Ge、p-t-Bu和_p-PhO）的情况类似。这些聚合物是可溶性的，它们的分子量达到1 × 106至3 × 106。它们中的一些比聚（二甲基硅氧烷）更透气。几种乙炔（例如，ClC-n-C_6 H_（13）和HCUC-t-Bu）与MoOCl_4-n-Bu_4 Sn-EtOH发生活性聚合。而苯乙炔（PA）不以活性方式终止，PA中的邻位取代基或多或少地抑制终止和链转移。具有庞大邻位基团的PA（例如，CF 3和Me 3Ge）尤其经历几乎理想的活性聚合。
This article reviews recent topics on the polymerization of substituted acetylenes, focusing on the synthesis of poly(diphenylacetylenes) and the living polymerization of phenylacetylenes. Diphenylacetylene (DPA) polymerizes with TaCls-n-Bu4Sn to give a polymer which is thermally very stable but insoluble in any solvents. DPAs with various groups (e.g.,p-Me3Si,m-Me3Ge, p-t-Bu,and_p-PhO) polymerize similarly. These polymers are soluble and their M¯w's reach 1 × 106 to 3 × 106. Some of them are more gas-permeable than poly(dimethylsiloxane). Several acetylenes (e.g., ClC -n-C6H13 and HCUC-t-Bu) have been found to undergo living polymerization with MoOCl4-n-Bu4Sn-EtOH. Whereas phenylacetylene (PA) does not polymerize in a living fashion, ortho-substituents in PA more or less suppress termination and chain transfer. PAs with bulky ortho groups (e.g., CF3 and Me3Ge) especially undergo virtually ideal living polymerization.
