    • A method for producing poly-o-hydroxy amides by conversion of an activated dicarboxylic acid derivative with a bis-o-aminophenol. A solution of the activated dicarboxylic acid derivative is added to a solution of the bis-o-aminophenol in a lactone, and a tertiary amine is added to the resulting mixture, wherein the lactone has the following structure: ##STR1## where A is--(CR.sup.1 R.sup.2).sub.m --or--(CR.sup.3 R.sup.4).sub.n --NR.sup.5 --, R.sup.1 to R.sup.5 are independent of one another R.sup.1 and R.sup.2 are hydrogen, alkyl with 1 to 7 carbon atoms (linear or branched), --CO(CH.sub.2).sub.p CH.sub.3, or --COO(CH.sub.2).sub.p CH.sub.3, with p=0 or 1, R.sup.3 and R.sup.4 are hydrogen or alkyl with 1 to 3 carbon atoms (linear or branched), R.sup.5 is hydrogen or methyl, m is a whole number from 2 to 11, and n is a whole number from 1 to 3.
    • 通过活性二羧酸衍生物与双邻氨基苯酚的转化制备聚邻羟基酰胺的方法。 将活化的二羧酸衍生物的溶液加入到内酯中的双邻氨基苯酚的溶液中,向所得混合物中加入叔胺,其中内酯具有以下结构:其中 A是 - (CR 1 R 2)m - 或 - (CR 3 R 4)n -NR 5 - ,R 1至R 5彼此独立地R 1,R 2是氢,具有1至7个碳原子的直链或支链烷基, pCH 3或-COO(CH 2)p CH 3,其中p = 0或1,R 3和R 4是氢或具有1至3个碳原子的直链或支链的烷基,R 5是氢或甲基,m是从2到 11,n为1〜3的整数。
