摘　　要：通过偏苯三甲酸酐制备 1,2 ,4-苯三甲酰氯 ,再以二苯醚 (DPE)、1,2 ,4-苯三甲酰氯 (TMAC)为单体 ,无水AlCl3 /二氯乙烷 (DCE) /N -甲基吡咯烷酮 (NMP)为催化剂溶剂体系 ,在Friedel-Crafts亲电聚合条件下合成了含羧基侧基的聚芳醚酮酮树脂 (PEKK) ,进行了耐溶剂性试验 ,测定了其酸值及粘度 ,同时利用X -射线衍射、IR、DSC、TG等分析技术研究了含羧基侧基的聚芳醚酮酮树脂 (PEKK)的结构和性能 .研究结果表明 :该聚合物是可溶性无规低聚物 ,聚合物含有羧基侧基 ,可望成为耐高温性能分离膜、离子交换树脂 ,同时可作为交联聚合物、接枝聚合物及其它特种高分子材料的中间体 ,而且通过二元或三元聚合来改变交联点、接枝点的密度 。TMAC was prepared by reaction of benzene-1,2,4-tricarboxylic acid-1,2-anhydrid and SOC1 2,then polyaromatic ether ketone ketone containing carboxy on side chain was synthesized from DPE and TMAC by Friedel-crafts electrophilic polymerization. The polymer′s structure and properties were investigated by many analytic methods.It is shown that the polymer is amorphous, soluble in mang solvents at room temperature with low molecular weight, the polymer is also an intermediate product of crosslinked copolymer and grafted copolymer.It can supply with a good basis for getting poly(aryl ether ketone)s crosslinked,grafted and other special polymers with various structures and function by changing crosslinked density and grafted density through binary copolymerization or trimerization.
