在无水AlCl3及N-甲基吡咯烷酮(NMP)/1,2-二氯乙烷(DCE)复合溶剂的存在下,将含砜基芳二醚类单体与含偶氮苯结构芳二甲酰氯进行低温付-克缩聚反应,合成了一类新型含偶氮结构聚芳醚砜醚酮酮树脂。用IR、TG、WAXD及元素分析等技术进行了结构表征和性能测试。结果表明:所合成的聚合物树脂具有预期结构且为非晶态聚合物;在N2气氛中质量损失5%的温度(Td)分别为445～463℃;聚合物除了能在浓硫酸、CF3COOH/CHCl3等强极性质子型溶剂中溶解外,还能溶解于N-甲基吡咯烷酮(NMP)、N,N-二甲基甲酰胺(DMF)、二甲基亚砜(DMSO)等强极性非质子型溶剂中,也能在普通溶剂,如氯仿(CHCl3)、1,2-二氯乙烷(DCE)、四氢呋喃(THF)等中溶解。
In the presence of anhydrous AlCl3 and NMP / 1, 2-dichloroethane (DCE) complex solvent, the sulfone-containing aryl ether monomer was reacted with azobenzene structure aryl dimethyl A series of novel azo-containing poly (aryl ether sulfone ether ketone) resins were synthesized by the acid-condensation reaction of acyl chloride at low temperature. Structural characterization and performance testing were performed using techniques such as IR, TG, WAXD and elemental analysis. The results show that the synthesized polymer resin has the expected structure and is an amorphous polymer. The temperature (Td) of 5% mass loss in N2 atmosphere is 445 ~ 463 ℃, respectively. Besides the polymer can be concentrated in concentrated sulfuric acid, CF3COOH / CHCl3 and other highly polar protic solvents, but also soluble in N-methyl pyrrolidone (NMP), N, N-dimethylformamide (DMF), dimethyl sulfoxide (DMSO) In aprotic solvents, it can also be dissolved in common solvents such as chloroform (CHCl3), 1,2-dichloroethane (DCE), tetrahydrofuran (THF) and the like.
