摘　要：用实时傅里叶变换红外光谱仪（FTIR）对乙烯基硅橡胶和含氢硅油的加成聚合过程进行了表征，得到了基团浓度消耗比随反应时间变化的曲线。结果表明，在反应过程中，硅氢基与乙烯基的浓度减少呈非线性关系，这可能是硅氢基在反应过程中与空气中的物质进行了反应，从而在消耗量上较乙烯基多的缘故。

Abstract：By using real time FTIR, the additive polymerization process of hydrogen silicone with vinyl silicone rubber was monitored in- situ. According to peak area of function group in FTIR spectroscope, the different conversion time curves of [SiH] and [CH CH2]during the reaction process were got and its reason was presented reasonably
