摘要
聚二甲基硅烷(PDMS)具有不溶不熔的特性,本文使用热裂解-气相色谱-质谱(Py-GC-MS)研究了PDMS热裂解行为.通过对2种PDMS热裂产物差异的比较,试图获取与PDMS化学结构特征相关的信息,为聚碳硅烷(PCS)原料质量控制标准的制订提供基础信息.
Polydimethylsilane （PDMS）has the characteristics of none dissolving and none melting. In this paper,the Pyrolysis-gas chromatography-mass spectrometry （Py-GC-MS） was used to study on the pyrolytic behavior of PDMS. The differentiation of PDMS pyrolytic products were compared and the related chemical structural informations were got,which would offer the basic informations of standard making for the Polycarbosilane （PCS） quality control.
