摘要
以MeViSiCl2、MeHSiCl2和MeSiCl3为原料,采用先部分水解再氨解的方法制备了硅氧氮陶瓷先驱体。利用FT-IR、1H-NMR、29Si-NMR、GPC以及TGA对聚合物先驱体的结构和热性能进行了表征。结果表明:合成的硅氧氮烷在DCP固化2 h后具有77.7%的陶瓷产率。
The polymer precursor for silicon oxynitride ceramic was prepared by partial hydrolysis of MeViSiCl2 、MeHSiCl2 and MeSiCl3 followed by ammonolysis reaction of the hydrolyzed intermediates with NH3.The structure and thermal properties of the polymer precursor were studied by means of FT-IR,1H-NMR,29Si-NMR,GPC and TGA,which indicated that the ceramic yield of the polymer precursor doped with DCP cured for 2 h was 77.7%.
