再沉淀—热酰亚胺化法制备聚酰亚胺粒子

Polyimide particle by Reprecipitation-thermal Imidization method

以对位均苯二甲酯二酰氯和N,N′-二氨基二苯醚为单体通过再沉淀法制备了聚酰胺酯粒子,再通过热亚胺化得到聚酰亚胺粒子,并简单分析了聚酰胺酯的热亚胺化及其热稳定性。用TEM、sEM和红外光谱分析技术对产物进行了表征。

T Taking the monomers of 2,5—Bis(methoxycarbonyl) terephthaloyl chloride(p—PMDC) and 4,4'—Diaminodiphenyl ether,the poly(amide methyl ester)s particle was prepared by reprecipitation—thermal imidization method. In addition to the properties of the precursor poly(amic ethylester)s,a simple thermal study of the imidization process and the stability is presented.The TEM and SEM and IR techniques were used to characterize the product.
