| 摘 要： | <正> 由苯乙烯与二氧化硫共聚合生成的聚(苯乙烯砜)是一种良好的耐干法刻蚀的正性电子束阻蚀剂。近年来,国内外对其聚合条件以及作为阻蚀剂的物化性能等有较多的研究。但关于其热性能的研究报道甚少。Bowden等研究聚(苯乙烯砜)热降解时,发现其热分解温度在290℃以上。而国际商用机械公司(IBM)的报告则认为在135℃左

| Abstract: | In this work the thermal degradetion of poly(styrene sulfone) has been studied by differential scanning calorimeter (DSC) and thermogravimetric analyzer (TGA). Poly-(styrene sulfone) shows a two-step degradation mechanism, the initial degradation occuring in the temperature range 120-200℃ and major degradation taking place at higher temperature. Isothermal degradation of poly(styrene sulfone) .has also been studied. Above 270 ℃ the kinetics of the thermal degradation are first order with an activation energy of 63-64 KCal/mol. Below 270℃ the kinetics are complex with an activation energy of 14 KCal/mol. |
