聚芳醚醚酮酮的合成与表征
SYNTHESIS AND CHARACTERIZATION OF POLY(ARYL ETHER ETHER KETONE KETONE)
【摘要】 以对二溴苯和苯酚为原料合成高纯度1,4-二苯氧基苯(DPB),以1.2-二氯乙烷(DCE)为溶剂,无水三氯化铝/N、N-二甲基甲酰胺(DM F)为复合催化溶剂体系,与对苯二甲酰氯(TPC)或间苯二甲酰氯(IPC)进行溶液低温缩聚,得到一类聚芳醚醚酮酮(PEEKK)聚合物。用FT-IR,1H-NM R,DSC,TGA,W AXD等分析技术对聚合物进行表征。结果表明,该聚合物有较好的结晶性和良好的热稳定性。
【Abstract】 1,4-dipheoxylbenzene(DPB) was prepared by 1,4-dibromobenzene and phenol.A novel poly(aryl ether ether ketone ketone)(PEEKK) was prepared by electrophilic polycondensation of 1,4-dipheoxylbenzene(DPB) with terephthaloyl chloride(TPC) or isophthaloyl chloride(IPC) in 1,2-dichloroethane in the presence of AlCl3 and DMF.The polymers were characterized by IR,WAXD,DSC,TGA.The result shows that the polymers are crystalline and high thermly stability.
