摘要
以1,4-双-(4′卤苯酰基)苯和4′4-二氨基二苯醚为底物,加入钯催化剂Pd2(dba)3及其配体BINAP,通过Hartwig-Buchwald缩聚反应合成了新型高性能材料———聚亚胺醚酮(PIEK).PIEK的一般性能由DSC,TG等测定,研究表明:该聚合物表现出较高的玻璃化转变温度(Tg>200℃)、良好的热稳定性(TD>500℃)及良好的溶解性能.
Poly(imino ether ketone) (PIEK), as a new High-Performance polymer,has been synthesized via palladium-catalyzed polycondensation of 1,4-bis-(4-bromobenzoyl)benzene with 4,4'-diaminodiphenyl ether. The thermal property was studied by DSC and TG. The results indicated that PIEK showed good thermal stability with high decomposition temperature and good solubility in common orgarlic solvents.
