| 摘要: |
| 由聚二甲基硅烷(PDMS)与3%～7%wt聚氯乙烯(PVC)共热解反应生成的聚碳硅烷(PC-P)，是制备力学性能优良的低电阻率碳化硅纤维的先驱体。研究了PC-P先驱体的合成条件，利用GPC、IR、XPS、元素分析等手段对PC-P先驱体的组成与结构进行了分析，并初步探讨了PDMS与PVC反应机理。 |

| Abstract: |
| Polycarbosilane(PC-P), which is a useful precursor for Silicon Carbide fiber with high mechanical properties and low specific resistance, was synthesized using polydimethysilane(PDMS) and 3%～7%wt polyvinychloride(PVC). The synthesizing condition for PC-P was determined. The composition, structure and property of PC-P were studied by element analysis, IR, XPS and GPC. The reaction mechanism was preliminarily probed. |
| Keywords: SiC fiber polycarbosilane polyvinychloride low specific resistance |
