摘要
采用差示扫描量热仪和傅立叶红外光谱对聚甲基硅次乙炔基硅烷(MSE)等温(160、170、180℃)预处理过程进行了研究。结果表明:MSE等温处理过程中发生氢硅化反应,反应程度约为33%;相对反应程度达到95%时,所需时间分别为173(160℃)、93(170℃)和48(180℃)min;预处理时间t与处理温度T之间满足关系t(T)/t(T+10K)=2∶1。
The isothermal pretreatment process of Poly[-(methylsilylene) ethynylene3 (MSE), at 160, 170 and 180℃ respectively, has been investigated by means of differential scanning calorimeter and Fourier transformed infrared spectroscopy. The results showed that hydrosilylation of MSE proceeded on isothermal process with the reactive degree of approximately 33%; the pretreatmeat time was 173(160℃), 93(170℃) and 48(180℃) rain when the relative extent of re- action achieved 95 % and pretreatmeat time t and temperature T met the relationship t(T)/t(T+ 10K)= 2:1.
