聚二甲基硅烷的合成及光谱分析

Studies on the Synthesis and Spectra Analysis of Polydimethylsilane

以二甲基二氯硅烷（ （ＣＨ３）２ＳｉＣｌ２） 为原料， 通过Ｗüｒｔｚ 还原反应合成出聚二甲基硅烷。实验表明： 纯度高的原料使产物产率大幅提高， 用ＵＶ 和ＦＴ－ ＩＲ 对聚二甲基硅烷的结构进行表征。

Polydimethylsilane (PDMS) was synthesized with dimethyldichlorosilane (DMDCS) by Würtz coupling reaction.It was observed by many experiments that the production,structure and composition of PDMS were affected by the pureness of DMDCS,sodium and reaction condition.The structure of PDMS was characterized by UV and FT IR spectra.
