| 摘 要： | 通过甲基乙烯基二氯硅烷及甲基氢二氯硅烷氨解并以NH4C l催化制备了四种含活性基团的有机硅氮烷。对其紫外光(UV)固化性能、机理及热裂解行为进行了研究。结果表明,紫外光可以有效地引发含活性基的有机硅氮烷固化,固化时主要发生N-H、-CH=CH2间的反应;增大低聚物中S i-H含量和硅氮烷的分子量,均可提高其裂解后的陶瓷产率。

| Abstract: | Four polysilazanes containing reactive groups were synthesized via ammonolysis of MeViSiCl_2 and MeHSiCl_2,and the UVcuring and pyrolysis behaviors for different polysilazanes were also investigated by using IR spectroscopy and TGA technology.The results indicate that the polysilazanes can be cured mainly via the reactions among N-H and vinyl reactive groups.The TGA results of the cured polysilazanes show that the ceramic yield increase with the increasing in molecular weight and the content of Si-H groups in the polysilazanes. |
