中文摘要：

采用热分析方法（TG，DTA）、热分解气相色谱和红外光潜等联合手段，对双酚A（4-4’-二羟基二苯基丙烷）和四溴双酚A（2．2-二[3，5-二溴-4羟基苯基]丙烷）的热稳定性及热分解反应动力学进行了研究，发现它们的稳定性和分解机理与取代基性质、分子结构的对称性有明显关系．并对其稳定性、热解机理从电荷分布出发进行了理论分析．

英文摘要：

Thermal decomposition kinetics of 4,4＇-LDihydroxydiphenyl propane and 2,2-Bis （3,5.-dlbromo 4-hydroxyophenyl） Propane has been studied by means of DTA, TG, IR and Thermal cracking gas chromatography. It was found that their thermo-stability and decomposition mechanism have relations to the character of their substituting group. Their rate equation of thermal decomposition reaction was established, and the thermal decomposition kinetic parameters were obtained. The decomposition mechanism and stability were theoretically discussed on the basis of charge distribution.
