decomposition

Therrnogravimetric analysis at heating rates 5 , 10 , 15 and 20 c / min was used to study the decomposition kinetics of the pdms / pma ipn in ni and in air by using tg and dtg , and the upper limit of the temperature was 700 c . it was found that ipn began to decomposite at 350 c . the process of the thermal degradation was multiple steps , the curve of the rate of thermal decomposition had two peaks , one of which lied between 400 c ~ 420 c and the other lied between 500 c ~ 540 c , the result corresponded to the components of ipn 在熱分解動力學研究中,通過在兩種氣氛中,分別以5 、 10 、 15和20 min四種升溫速率條件下,采用tg - dtg聯動測試, ipn材料在350開始熱分解。熱分解速率存在兩個峰值,一個分解峰值在400 420之間,另一個在500 540之間,這與ipn結構中包含兩組分相對應,同時發現當緩慢升溫時,特別是在空氣氣氛中,兩個分解峰減弱,熱分解趨向于一個連續過程。
