采用热重分析（TGA）和差热分析（DTA）评价了无规聚丙烯（APP）热溴化得到的溴化无规聚丙烯（BAPP）的热行为。结果表明，随着溴含量的增加，初始分解温度（IDT）和焦炭产率增加，而整体过程分解温度（IPDT）呈下降趋势。对惰性和氧化性气氛中的这些值进行了比较研究。差热分析表明，随着溴化度的增加，起始分解温度（ODT）和玻璃化转变温度（Tg）升高。并对产生这种现象的可能原因进行了讨论。
Thermal behavior of brominated atactic polypropylene (BAPP), obtained by thermal bromination of atactic polypropylene (APP), was evaluated by thermogravimetric analysis (TGA) and differential thermal analysis (DTA). It was found that the initial decomposition temperature (IDT) and char yield increase with the increase in bromine content while integral procedural decomposition temperature (IPDT) showed a decreasing trend. A comparative study of these value in inert and oxidative atmospheres has been made. DTA study shows that onset decomposition temperature (ODT) and glass transition temperature (Tg) increase with the increase in degree of bromination. The possible reasons for the occurring phenomena have been discussed.
