An azido-terminated polyhedral oligomeric silsesquioxane (POSS) compound, octakis(azidopropyl-3-oxycarbonyl-1-decyl-10-thiopropyl-3-)POSS (OADTP), is synthesized and characterized. POSS-polytriazole (PTA) resins are prepared from an azide, an alkyne monomer, and OADTP. The toughening effect of OADTP on PTA resins is analyzed by impact performance test and electronic microscope characterization, and the thermal performance of resins is measured by thermogravimetric analysis and dynamic mechanical analysis. The results show that the addition of the POSS can improve the mechanical properties of PTA resins. The impact strength of POSS-PTA resins first increases and then decreases with the increase in the POSS compound, and the maximum one arrives at 54.8 kJ m −2 which increases by 44.2% as compared to 38 kJ m −2 of the PTA resin. A good thermal stability remains in POSS-PTA resins.

聚三唑树脂可通过叠氮基末端的多面体低聚倍半硅氧烷（OADTP）增韧

合成并表征了叠氮基封端的多面体低聚倍半硅氧烷（POSS）化合物，八烷基（叠氮基丙基-3-氧羰基-1-癸基-10-硫丙基-3-）POSS（OADTP）。POSS-聚三唑（PTA）树脂由叠氮化物，炔烃单体和OADTP制备。通过冲击性能测试和电子显微镜表征分析了OADTP对PTA树脂的增韧作用，并通过热重分析和动态力学分析测量了树脂的热性能。结果表明，添加POSS可以改善PTA树脂的机械性能。POSS-PTA树脂的冲击强度首先随着POSS化合物的增加而增加，然后降低，并且最大冲击强度达到54.8 kJ m -2，与PTA树脂的38 kJ m -2相比增加了44.2％。
