摘要
以1,4-双-(4′-溴苯酰基)苯和含柔性侧基的芳香环二胺基化合物6-[2-(2-十一烷基-1-咪唑基)乙烷]-1,3,5-三嗪-2,4-二胺为单体,通过钯催化的胺基化反应缩聚合成了新型含柔性侧基的聚亚胺酮(PIK-T),其结构经1H NMR和IR表征。对PIK-T的DSC,TG和GPC分析结果表明,由于主链的芳香环及柔性侧基的引入,PIK-T在保持了PIKs聚合物优良的热稳定性的同时,溶解性能更加优良;分子量及其分布也较普通PIKs更具优势。
Novel poly（imino ketone）s with flexible side chain（PIK-T） was synthesized by the condensation polymerization of 1,4-bis-（4′-bromobenzoyl）-benzene and 2,4-diamino-6-[2-（2-undecyl-1-imidazolyl）ethyl]-1,3,5-triazine via Palladium-catalyzed aryl amination reacation.The structures were characterized by 1H NMR and IR.The main properties of PIK-T were investigated by DSC and TG.The molecular weight and molecular weight distribution of PIK-T were tested by GPC.The results showed that PIK-T exhibited the same performance,such as thermal stability,while the solubility,molecular weight and molecular weight distribution were better than the common PIKs.
