使用 DSC、IR研究了聚苯醚 /双柠康酰亚胺体系的固化反应过程 ,得到了固化反应的平均表观活化能 E为 184 .4 k J/ mol,反应级数 n接近 1.固化后体系的理化性质变化明显 (特别是不溶于氯仿 ) ,IR图谱的变化不显著 ,DSC行为与单独的聚苯醚相近 .
The curing reaction of poly (phenylene ether) / biscitraconimide system was studied by DSC and IR. The average apparent activation energy E of the curing reaction was 184.4 kJ / mol and the reaction order n was close to 1. Curing The physico-chemical properties of the latter system changed significantly (especially not in chloroform), the changes of IR spectra were not significant, and the DSC behavior was similar to that of polyphenylene ether alone.
