| 摘 要： | 利用沉淀聚合法,以均苯四酸二酐(PMDA)和4,4′-二氨基二苯醚(ODA)为单体,丁酮(MEK)和N-甲基吡咯烷酮(NMP)混合溶液为溶剂,在常温下,搅拌速度为500r/min,制备了聚酰亚胺的前驱体聚酰胺酸(PAA)。红外光谱表明,所得产物是聚酰胺酸。利用扫描电子显微镜(SEM)分析了混合溶剂的不同体积比对聚酰胺酸微粒子形貌的影响,结果表明,当MEK与NMP的体积比为8:1时,聚酰胺酸微粒子的平均粒径最大,为5.89μm。试制了聚酰亚胺(PI)微粒子,对其进行了SEM、红外光谱分析及热重(TG)分析。

| Abstract: | A kind of poly(amic acid) (PAA) microparticles was synthesized,with butanone (MEK) and N-methyl-2-pyrrolidone (NMP) as component solvent,from pyromellitic diahydride (PMDA) and 4,4'-diaminodiphenyl ether(ODA) by precipitation polymerization in room temperature and 500r/min ratio of mechanical agitation.Infrared (IR) spectrum suggested the success of poly(amic acid) microparticles.SEM analysising in morphology of microparticles showed that poly(amic acid) microparticles size increased with the increasing vol... |
