| 摘要: |
| 本文采用一种聚钛硅氧烷与聚碳硅烷反应，制得了Ti/Si 摩尔比为 0.10 的聚钛碳硅烷。该聚合物具有良好的成丝性与稳定性，经熔融纺丝，再经不熔化处理后，在氮气气氛保护下1300℃热处理后制得了高含钛量的碳化硅纤维。文中对聚钛硅氧烷的合成与结构，它与聚碳硅烷的反应过程及聚钛碳硅烷的热分解特性进行了分析与研究。 |

| Abstract: |
| The Polytitanocarbosilane with the molar ratio of Ti:Si=1:10 had been prepared by the reaction of polycarbosilane with polytitanosiloxane. This polymer had excellent spinnability and stability. After being melt spinning and unmelting treatment，followed by heat treatment at 1300℃ in the presence of nitrogen atmosphere，the SiC fiber with high molar ratio of Ti/Si was obtained. The synthesis and structure of cited polytitanosiloxane，its reaction process with polycarbosilane，and the pyrolytic properties of polytitanocarbosilane were examined and discussed. |
