摘要
以1,4-双-(4′-溴苯酰基)苯和2,2-双-[4-(4-氨基苯氧基)苯基]丙烷为单体,以三(二亚苄基丙酮)二钯为催化剂,1,1′-联萘-2,2′-二苯膦(BINAP)为配体,由钯催化的胺基化反应缩聚合成了含异亚丙基的聚亚胺醚酮(pr-PIEK),并通过微封装法制备了pr-PIEK空心微球.
Poly( arylene imino ether ketone) containing isopropylidene group(pr-PIEK) was synthesized by the condensation polymerization of 1, 4-bis-(4-bromobenzoyl) benzene and 2, 2-bis [ 4-( 4-aminophenoxy) phenyl] propane via palladium-catalyzed aryl amination reaction. The catalyst system was composed of tris (dibenzylideneaeetone) dipalladium and 2,2'-his (diphenylphosphino) -1,1 '-binaphthyl (BINAP). Additionally, the hollow microsphere of pr-PIEK was prepared .
