合成了由聚碳硅烷与四醇钛交联形成的新型聚钛碳硅烷，以研究将多元素有机金属聚合物转化为无机化合物的过程。通过红外光谱(IR)、凝胶渗透色谱(GPC)、数均分子量测量和29Si核磁共振(NMR)测量技术研究了该聚合物的化学结构。在1400℃和1700℃氮气中热解产物分别为微晶态碳化硅和晶态碳化钛。
The novel polytitanocarbosilane, formed by the cross-linking of polycarbosilane with titanium tetra-alkoxide, was synthesized to examine the process of converting a multielement organometallic polymer into an inorganic compound. The chemical structure of this polymer was investigated by the techniques of infra-red spectroscopy (IR), gel permeation chromatography (GPC), number average molecular weight measurements and29Si nuclear magnetic resonance (NMR) measurements. The pyrolysis products in N2gas at 1400° C and 1700° C were the microcrystalline and crystalline states of silicon carbide and titanium carbide, respectively.
