| 中文摘要 | 本研究利用熱重分析儀在氯氣環境下探討丙烯睛--丁二烯--苯乙烯三聚合物的熱 裂化行為,本實驗分別以四種不同動態加熱速率,5,10,20和40℃/min在100至 800℃溫度範圍內操作,並以五種恆溫加熱 350,375,400,425和450℃維持15分鐘。 本研究分別以Flynns與Freemans的模式加以解析其熱裂化行為,結果顯示,丙烯睛 --丁二烯--苯乙烯三聚合物以動態熱重分析法解析,其熱裂化活化能為42.7 kcal/mole;以恆溫熱重分析法解析,其熱裂化活化能為42.0 kcal/mole。 |
| 英文摘要 | In this study, the thermal degradation of acrylonitrile-butadiene- styrene terpolymer (ABS) were studied under N �� gas by using the thermogravimetry analyzer. The activation energies of thermal decomposition were evaluated by using Flynns' and Freemans' models, rrespectively. The experimental results showwed that the activation energy of dynamic heating of ABS resin were 42.7 kcal/mole. Moreover, The activation energy of isothermal heating of ABS resin were 42.0 kcal/mole. |
