由計含磷硬化劑苯磷醯二胺(PPD)與bisphenol A 型環氧樹脂預聚物(DER331)進行硬
化聚合反應,得到主鏈上含磷元素之環氧樹脂(PPDE). 利用DSC 探求硬化反應動力學參數,
DMA 觀察凝膠化時間及PPDE 玻璃轉移溫度的變化, 再利用TGA 在氮氣及空氣中進行熱裂
解實驗, 探討PPDE 之裂解溫度及殘餘量隨磷含量的關係, 再探討含磷量對LOI 值的影響.

The curing reaction of a bisphenol A type epoxy prepolymer(DER331)coupled
with a curing agent containing phosphorus ( phenyl phosphorodiamidate ) was c
onducted to obtain an epoxy resin containing phosphorus, PPDE. The kineticpara
meters of the curing reaction were obtained by DSC analysis. The gel point in
the curing reaction and the Tg changes of PPDE were observed by DMA analysis.
The thermal degradation behavior of these phosphorus PPDE with different conte
nts of phosphorus were examined by TGA analysis. The effectof the phosphorus c
intent in PPDE on the LOI value was also studied.
