  带有碳硅烷链段的聚氨酯的合成与表征†

  摘要：

  合成了带有碳硅烷链段（1a–c）的新型聚氨酯。将它们的热和机械性能与相应的带有碳基骨架的参考聚氨酯（2a–c）进行了比较。通过DSC和TGA研究了这些聚氨酯的热性能。通过用硅（1a–c）取代碳原子，玻璃化转变温度显着降低。此外，发现1a–c的热分解温度与2a–c相当。此外，杨氏模量1a–c低于杨氏模量2a–c。本文证明了碳硅烷单元作为制造新型聚氨酯的软链段的巨大潜力。

  A series of analogous nitratomethyl compounds of carbon and silicon of the formula types Me3EICH2ONO2 (1a/1b), Me2EI(CH2ONO2)(2) (2a/2b), MeEI(CH2ONO2)(3) (3a/3b), (CH2)(4)EI(CH2ONO2)(2) (4a/4b), and (CH2)(5)EI(CH2ONO2)(2) (5a/5b) were synthesized [El = C (a), Si (b); (CH2)(4)EI = (sila)cyclopentane-1,1-diy1; (CH2)(5)EI = (sila)cyclohexane-1,1-diy1]. All compounds were characterized by using NMR, IR, and Raman spectroscopy and mass spectrometry. In addition, the crystal structures of Me2C(CH2ONO2)(2) (2a), (CH2)(4)C(CH2ONO2)(2) (4a), Me2Si(CH2ONO2)(2) (2b), and (CH2)(5)Si(CH2ONO2)(2) (5b) were determined by single-crystal X-ray diffraction. The gas-phase structures of the C/Si analogues la and lb were determined by electron diffraction and compared with the results of quantum chemical calculations at different levels of theory. The thermal stabilities of the C/Si pairs la/lb-5a/5b were investigated by using DSC. In addition, their friction and impact sensitivities were measured with standard BAM methods. The extreme sensitivities of the silicon compounds lb 5b compared to those of the corresponding carbon analogues 1a 5a were discussed in terms of the structures of the C/Si analogues and possible geminal Si center dot center dot center dot O interactions.

  Four silanes based on the neo-pentane skeleton Me4-xSi(CH2R)(x) containing carbamate groups (x = 14, R = OC(O)NH2) have been prepared via the corresponding alcohols Me4-xSi(CH2OH)(x), starting from the chlorosilanes Me4-xSiClx. Subsequent nitration leads to the corresponding primary nitrocarbamates (R = OC(O)NHNO2), examined for the purpose as potential energetic materials, including the silicon analogue of pentaerythritol tetranitrocarbamate (sila-PETNC) and a siloxane based nitrocarbamate side-product. All compounds were thoroughly characterized by spectroscopic methods including X-ray diffraction. Thermal stabilities and sensitivities toward impact and friction were examined, as well as detonation values by calculating energies of formation using the EXPLO5 V6.02 software.
