| 摘 要： | 采用热重分析技术研究了4种聚-α-甲基苯乙烯原料和其它微球壳层材料的热降解温度。研究表明,聚-α-甲基苯乙烯原料主要失重温度范围为220～340℃,等离子体辉光放电涂层材料的降解温度为350～450℃。升温速率在20℃/min和30℃/min时,降解温度基本相同,升温速率不影响降解的温度范围,低于20℃/min时,随着升温速率升高,降解温度升高。

| Abstract: | Thermal gravity analysis was applied to obtain the thermal pyrolysis behaviour of four kinds of poly (alpha-methylstyrene) of different average relative molecular mass. Experiments indicated that the pyrolysis temperature of poly (alpha-methylstyrene) covered 220 ℃ to 340 ℃, and that of glow discharge polymer covered 350 ℃ to 450 ℃. Degradation temperature kept fixed at the rate of 20 ℃/min and 30 ℃/min, and the temperature increased when the rate was no more than 20 ℃/min. |
