含异亚丙基聚亚胺醚酮空心微球的制备

Preparation of Hollow Microsphere of Poly(arylene imino ether ketone) Containing Isopropylidene Group

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 .
