Pyrolysis polycondensation of polysilane has been executed at different temperatures, pressures under catalyst/ no catalyst conditions in an autoclave reactor. Progress of polymerization was followed as a function of several process parameters such as temperature, pressure, intrinsic viscosity, average molecular weight and catalyst. Process analysis revealed that temperature and pressure had significant influence on the structure and properties of polycarbosilane. Gel permeation chromatographic data and intrinsic viscosity measurements confirmed the formation of polycarbosilane with average molecular weight up to 6300 Da. Average molecular weight, conversion and yield increased with use of catalyst. FT-IR and ²⁹Si NMR established that structural formation and bonding network during the silane to carbosilane transformation as a function of process conditions.

聚硅烷的热解缩聚已在高压釜反应器中在催化剂/无催化剂条件下的不同温度、压力下进行。聚合反应的进展是作为几个工艺参数的函数，如温度、压力、特性粘度、平均分子量和催化剂。工艺分析表明，温度和压力对聚碳硅烷的结构和性能有显着影响。凝胶渗透色谱数据和特性粘度测量证实了平均分子量高达 6300 Da 的聚碳硅烷的形成。平均分子量、转化率和产率随着催化剂的使用而增加。红外光谱和²⁹Si NMR 确定了硅烷向碳硅烷转化过程中的结构形成和键合网络是工艺条件的函数。
