    • A method for preparing high molecular weight polyetherimide ester polymers comprising:(A) preparing a polyetherimide ester oligomer by coreacting(i) at least one diol,(ii) at least one dicarboxylic acid or an ester forming reactive derivative thereof, and(iii) a set of reactants selected from(a) (1) at least one high molecular weight poly(oxy alkylene)diamine, and (2) at least one tricarboxylic acid or a derivative thereof, or(b) at least one high molecular weight polyoxyalkylene diimide diacid, at elevated temperature and for a period of time effective to form said oligomer; and then(B) further polymerizing said oligomer by a solid phase polycondensation procedure comprising heating said oligomer at a temperature effective to further polymerize said oligomer to a high molecular weight polyetherimide ester polymer but below the melting point of said oligomer.The instant process is useful for forming high molecular weight polyetherimide ester polymers suitable for production of extruded and molded articles.
    • 一种制备高分子量聚醚酰亚胺酯聚合物的方法,包括:(A)通过(i)至少一种二醇,(ii)至少一种二羧酸或其形成酯的反应性衍生物,制备聚醚酰亚胺酯低聚物,和(iii) 一组选自(a)(1)至少一种高分子量聚(氧亚烷基)二胺的反应物,和(2)至少一种三羧酸或其衍生物,或(b)至少一种高分子量聚氧化烯 二酰亚胺二酸在升高的温度下和有效形成所述低聚物的时间段; 然后(B)通过固相缩聚方法进一步聚合所述低聚物,包括在有效使所述低聚物进一步聚合到高分子量聚醚酰亚胺酯聚合物但低于所述低聚物熔点的温度下加热所述低聚物。 该方法可用于形成适于生产挤出和模塑制品的高分子量聚醚酰亚胺酯聚合物。
