Polytitanocarbosilane(PTC),the precursor of SiC fiber containing Ti,has been synthesized directly from polysilane(PS)and titanium tetrabu-toxide(Ti(OBu)_4)without using any reaction promoter.In this reaction,PS was decomposed into polysilane of low molecular weight(LPS)containing Si—C skeleton and Si—H bonds.Then PTC was obtained by thereaction of Si—H bonds in LPS with Ti(OBu)_4 accompanied by theconversion of Si—Si skeleton in LPS into Si—C skeleton.In this paper,the synthesis process and structure...

从聚硅烷(PS)与钛酸丁酯。(Ti(OBu)_4)出发,不采用任何反应促进剂直接合成了含钛碳化硅纤维的先驱体聚钛碳硅烷(PTC)。在这一反应中,PS 首先裂解成含Si—C 骨架与Si—H 键的低分子聚硅烷(LPS)。然后,由LPS 中的Si—H 键与Ti(OBu)_4的反应以及LPS 的Si—Si 骨架裂解转化为Si—C 骨架的反应制得了PTC.本文对这种新合成法所涉及的反应过程进行了研究,并比较了新旧两法得到的PTC—1与PTC—Ⅱ的结构异同,报告了以新法制得的PTC—Ⅱ为先驱体得到的含钛碳化硅纤维的优良性能。

Polytitanocarbosilane(PTC-Ⅲ),the precursor of SiC fiber containing Ti,hasbeen synthesized directly from polysilane(PS)and titanium tetrabutoxide Ti(OBu)_4 without us-ing any reaction promoter.In this reaction,PS was decomposed into polysilane of low molecu-lar weight(LPS)containing Si-C skeleton and Si-H bonds.Then PTC was obtained by the re-action of Si-H bonds in LPS with Ti(OBu)_4 accompanied by the conversion of Si-Si skeletonin LPS into Si-C skeleton.SiC fiber containing Ti with good mechanical...
