| Abstract: | 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. |
