【摘要】 将合成的N-(4-氯苯基)-对氯苯甲酰胺,与4,4’-二氟二苯甲酮及硫化钠作为反应单体,在氮甲基吡咯烷酮(NMP)中进行常压缩聚,制备了聚芳硫醚酮/酰胺(PASK/A)共聚物;采用红外、紫外光谱、核磁共振对聚合物链结构进行了表征,通过XRD表征聚合物聚集态结构,对聚合物进行DSC和TG分析,发现该聚合物保持了聚芳硫醚酮优良的耐热性能;但改善和提高了聚芳硫醚酮的溶解性能。更多还原

【Abstract】 Copoly(polyarylene sulfide keteone/polyarylene sulfide amide)was synthesized at normal pressure by the polycondensation of sodium sulfide(Na2S·xH2O) with N-(tetra-chlorphenyl)-parachlorobenzoyl amide and 4,4-difldibenzophenone(DFBP) in NMP.IR,UV spectra and H1-NMR analytical were carried out to characterize the structure of copolymers.Thermal properties of the copolymer were measured by means of DSC and TG.The results were showed that PASK/A retained excellent thermal stability and it had a bit of improvement of solubility to PASK.更多还原
