抄録

This review article surveys the synthesis and properties of substituted polyacetylenes, especially those which exhibit high gas permeability, such as poly [1- (trimethylsilyl) -1-propyne] [poly (TMSP)] and poly (diphenylacetylene) [poly (DPA)] derivatives. Poly (TMSP) having high molecular weight up to around 1 × 10⁶ can be obtained by the metathesis polymerization of TMSP catalyzed by TaCl₅ and NbCl₅. This polymer is characterized by good solubility in many common solvents, formation of tough films by solution casting, a high glass transition temperature (> 250 °C), and fairthermal stability. Its oxygen permeability (Po₂) at 25 °C reaches ca. 6, 000 barrers, which is the highest value of all existing polymers. The gas permeation properties of poly (TMSP) are reviewed. The TaCl₅/n-Bu₄Sn system is effective for the polymerization of DPAs. Most of the produced polymers are soluble in organic solvents, thermally highly stable, and film-forming by solution casting. Interestingly, large Po₂ values (1, 100 barrers) are observed with poly (DPAs) bearing bulky spherical para-substituents. Desilylation of p-Me₃Si-containing poly (DPA) membrane yields poly (DPA) membrane, which shows high Po₂ of-6, 000 barrers.
