Abstract A new kind of asymmetrical ether diamine, 3,4′-bis(4-aminophenoxy)benzophenone (BABP), was synthesized from the nucleophilic substitution reaction of 4-chloronitrobenzene and 3,4′-dihydroxybenzophenone in the presence of potassium carbonate, followed by catalytic reduction with SnCl2·6H2O and concentrated hydrochloric acid. The prepared diamine was employed in the preparation of a novel polyimide
摘要在碳酸钾存在下,由4-氯硝基苯与3,4'-二羟基二苯甲酮的亲核取代反应合成了一种新型的不对称醚二胺3,4'-双(4-氨基苯氧基)二苯甲酮(BABP),然后用SnCl2·6H2O和浓盐酸催化还原。所制备的二胺通过两步法与BTDA缩聚,用于制备含有不对称二芳基醚链段的新型聚酰亚胺。所得的聚酰亚胺表现出优异的溶解性,成膜能力和高耐热性。
