摘要
研究了四溴双酚─Ａ（ＴＢＡ）、ＴＢＡ的精制品、ＴＢＡ精制品与Ｓｂ２Ｏ３、聚丙烯（ＰＰ）、聚苯乙烯（ＰＳＴ）的热分解式反应。发现，ＴＢＡ分解时放热，反应速率常数比六溴环十二烷较小，与Ｓｂ２Ｏ３混合后反应变化明显，对于ＰＰ热分解有较明显的影响。
In the paper,the thermodecompose of reaction of the tetrabromo diphonel-A (TBA )and the rectifying product of TBA and the mictures of TBA polypropglene (PP) .T BA-poly styrene (PST) were studied. The decompose of TBA is a exothermic reaction,and it’s reaction rate constant is smaller than hexa bromocy clododeeane’s. When added Sb2O3,the reaction change is obvious. There is obvious influence too for PP.
