亚胺化工艺对PMDA-ODA型线性聚酰亚胺模塑粉制备的影响

Effect of Imidation Process on the Preparation of PMDA-ODA Linear Polyimide Moulding Powder

研究了均苯四甲酸二酐(PMDA)-二氨基二苯醚(ODA)型线性聚酰亚胺模塑粉的制备工艺,通过扫描电子显微镜(SEM)分析、红外光谱(FT-IR)分析以及X射线衍射(XRD)分析对亚胺化方法进行了对比研究。

The preparation process of PMDA-ODA linear polyimide molding powder was studied in this paper.The imidization methods were compared by scanning electron microscopy(SEM),infrared spectroscopy(FT-IR)and X-ray diffraction(XRD).
