摘要
为制备高纯度的双马来酰亚胺 ,减少双马来酰亚胺单体中杂质对单体本身反应活性及其性能的影响 ,采用柱上层析法提纯粗双马来酰亚胺 ,经高效液相色谱分析纯度达99.61 % ;通过晶体结构分析研究了其晶体结构 。
The impureties in bismaleimide(BMI)monomer have many bad effects on the reactivity of the monomer and properties of BMI resin.The BMI monomer is purified by column chromatography and its purity is99.61%(analysized by HPLC).A single crystal with a suitable size was used for X-ray diffraction study.the crystal structure and molecule structure orthodiagram of this monomer are presented in this paper.
