A method for producing a reactive intermediate composition, including: reacting a substituted phthalic anhydride of the formula (I) with a diamine of the formula H2N—R—NH2 in the presence of an aromatic dianhydride in an amount of 10 to 50 mole percent based on the total moles of anhydride functionality in the reaction; wherein the reacting is conducted in an aprotic solvent in a reactor, under conditions effective to produce the reactive intermediate composition; and wherein X comprises a halogen or a nitro group, and R comprises a C6-36 aromatic hydrocarbon group or a halogenated derivative thereof, a straight or branched chain C2-20 alkylene or a halogenated derivative thereof, or a C3-8 cycloalkylene or a halogenated derivative thereof.
一种生产活性中间体组合物的方法,包括在芳香族二酐存在下,使式(I)的取代邻苯二甲酸酐与式 H2N-R-NH2 的二胺反应,芳香族二酐的用量为反应中酐官能团总摩尔数的 10 至 50 摩尔%;其中,反应在反应器中的壬烷溶剂中进行,反应条件对生产反应性中间体组合物有效;其中X包括卤素或硝基,R包括C6-36芳烃基团或其卤代衍生物、直链或支链C2-20亚烷基或其卤代衍生物、或C3-8环亚烷基或其卤代衍生物。
