摘要
以均苯四酸二酐(PMDA)和4,4,-二氨基二苯醚(ODA)为单体,丁酮为溶剂,合成了均苯型的聚酰胺酸(PAA)粒子。通过SEMI、R、TG、DSC等手段对产物进行了表征,结果表明,制备的PAA粒子具有较好的形貌和优良的性能。
The polyamic acid(PAA) partcles was successfully synthesized from PMDA and ODA in the MEK.The product of PAA particles was characterized by SEM,IR,TG,DSC and The result showed that PAA with good morphology and good heat-resistant property can be synthesized in low boiling point blending solvent.
