  Microporous Cyanate Resins: Synthesis, Porous Structure, and Correlations with Gas and Vapor Adsorptions

  摘要：

  Three silicon and nitrogen-centered cyanate monomers tetrakis(4-cyanatophenyl)silane, tetrakis(4-cyanato-biphenyl)silane, and tris(4-cyanatobiphenyl)amine were designed and synthesized, which were then polymerized via thermal cyclotrimerization reaction to create highly porous cyanate resin networks with systematically varied nodes and linking struts. The chemical structures of monomers and polymers were confirmed by H-1 NMR, FTIR, solid-state C-13 CP/MAS NMR spectra, and elemental analysis. The products are amorphous with 5% weight-loss temperatures over 428 degrees C. The results based on N-2 and CO2 adsorption isotherms show that the pores in these polymers mainly locate in the microporous region, and the BET surface areas are up to 960 m(2) g(-1), which is the highest value for the porous cyanate resin reported to date. The nitrogen- and oxygen-rich characteristics of cyanate resins lead to the networks strong affinity for CO2 and thereby high CO2 adsorption capacity of 11.1 wt % at 273 K and 1.0 bar. The adsorption behaviors of H-2, CO2, benzene, n-hexane, and water vapors were investigated by correlating with the chemical composition and porosity parameters of the networks as well as the physicochemical nature of adsorbates.

  The synthesis and physical properties of new silicon‐containing polyfunctional cyanate ester monomers methyl[tris(4‐cyanatophenyl)]silane and tetrakis(4‐cyanatophenyl)silane, as well as polycyanurate networks formed from these monomers are reported. The higher crosslinking functionality compared to di(cyanate ester) monomers enables much higher ultimate glass transition temperatures to be obtained

  报道了新型含硅多官能氰酸酯单体甲基[三（4-（氰基苯基））硅烷和四（4-氰基苯基）硅烷）的合成和物理性能，以及由这些单体形成的聚氰尿酸酯网络。与二（氰酸酯）单体相比，更高的交联官能度使得能够通过热环三聚获得更高的极限玻璃化转变温度。通过将新单体与二（氰酸酯）单体（例如1,1-双（4-氰基苯基）乙烷）共固化，可以大大提高完全转化的能力。在这些聚氰尿酸酯网络中，硅的存在改善了其在高温下对快速氧化的抵抗力，在性能最佳的网络中，氮气下的焦炭收率高达70％，空气中的焦炭收率高达56％。在85°C下浸泡96 h后，所考察的含硅网络中的吸水率为4–6 wt％，远高于含碳和/或二（氰酸酯）类似物。©2013 Wiley Periodicals，Inc.
