An aromatic polyester amidejs produced by reacting hydroxyphenyl-aminophenyl-propane with aromatic dicarboxylic acid dihalide in the presence of an inert organic solvent, and bringing the organic solvent phase containing the mixture of the reaction products of the above reaction into contact with an aqueous phase containing an acid-acceptor, whereby completing polycondensation reaction. In order to control the dissolution of water into the organic solvent phase while maintaining an adequate level of miscibility between the organic solvent phase and the aqueous phase, a neutral salt of inorganic electrolyte, such as sodium chloride, is added to the aqueous phase containing the acid-acceptor.
在惰性有机溶剂存在下,使羟基苯基-氨基苯基-丙烷与芳香族二羧酸二卤化物反应,并使含有上述反应产物混合物的有机溶剂相与含有酸接受体的水相接触,从而完成缩聚反应,制得芳香族聚酯酰胺。为了控制水溶解到有机溶剂相中,同时保持有机溶剂相和水相之间足够的混溶性,在含有酸接受体的水相中加入无机电解质的中性盐,如氯化钠。
