Preparation method of titanium-containing polycarbosilane precursor
The invention belongs to the technical field of ceramic materials, and particularly discloses a preparation method of a titanium-containing polycarbosilane precursor. The preparation method comprises the following steps: firstly, carrying out rearrangement reaction on solid polycarbosilane and CH3SiCl3 monomers, then carrying out aminolysis reaction on a rearrangement product, and heating an aminolysis product to carry out coupling reaction, so as to prepare the titanium-containing polycarbosilane precursor. The preparation method of the titanium-containing polycarbosilane precursor provided by the invention has the advantages of simple preparation steps, mild conditions, convenience in regulation and control, lower cost and easiness in large-scale popularization and application.
本发明属于陶瓷材料技术领域，具体公开了一种含钛聚碳硅烷前驱体的制备方法。本发明制备方法先将固态聚碳硅烷与CH3SiCl3单体进行重排反应，之后重排产物再进行胺解反应，所得胺解产物加热进行偶联反应，制得含钛聚碳硅烷前驱体。本发明提供的含钛聚碳硅烷前驱体的制备方法制备步骤简单、条件温和、调控方便且成本较低，容易进行规模化推广应用。
