Poly(silylene arylacetylene) (PSA) is a kind of poly(arylacetylene) silicon‐containing resins with excellent heat resistance and good mechanical performances. In this article, the sulfur atom is introduced into the main chain of the PSA molecule to obtain a sulfur‐containing poly(silylene arylacetylene), named S‐PSA. By Williamson and Sonogashira reactions, bis(4‐ethynylphenyl)sulfide and bis(4‐ethynylphenyl)sulfone were synthesized. Thereafter, through Grignard reagent way, the poly(silylene ethynylene phenylene sulfide phenylene ethynylene) (PSESE) and poly(silylene ethynylene phenylene sulfone phenylene ethynylene) (PSESO₂E) were synthesized from bis(4‐ethynylphenyl)sulfide, bis(4‐ethynylphenyl)sulfone, and methylphenyl dichlorosilane. Poly(silylene ethynylene phenylene sulfoxide phenylene ethynylene) (PSESOE) was synthesized by the oxidation of PSESE. The structures and properties of these resins were characterized and the mechanical properties of the T300 reinforced composites were tested. The results show that the novel S‐PSA resins have excellent heat resistance and good mechanical properties, and could be used as resin matrices for high‐performance composites in high‐tech fields. © 2019 Wiley Periodicals, Inc.

含硫聚硅亚烷基芳基乙炔的合成与性能

聚（亚甲基芳基乙炔）（PSA）是一种具有优异的耐热性和良好的机械性能的含聚（芳基乙炔）硅树脂。在本文中，将硫原子引入PSA分子的主链中，以获得名为S-PSA的含硫聚（甲硅烷基芳基乙炔）。通过Williamson和Sonogashira反应，合成了双（4-乙炔基苯基）砜和双（4-乙炔基苯基）砜。此后，通过格氏试剂法，聚（亚乙基亚乙炔基亚苯基硫醚亚苯基亚乙炔基）（PSESE）和聚（亚乙基亚乙炔基亚苯基亚砜砜亚苯基亚乙炔基）（PSESO ₂E）由双（4-乙炔基苯基）硫化物，双（4-乙炔基苯基）砜和甲基苯基二氯硅烷合成。通过PSESE的氧化合成了聚（亚乙基乙炔基亚苯基亚砜亚苯基亚乙炔基）（PSESOE）。表征了这些树脂的结构和性能，并测试了T300增强复合材料的机械性能。结果表明，新型S-PSA树脂具有优异的耐热性和良好的机械性能，可在高科技领域用作高性能复合材料的树脂基质。©2019 Wiley Periodicals，Inc.J.Polym。科学，A部分：Polym。化学 2019，57，2324–2332
