双马来酰亚胺与4,4'-二氨基二苯醚预聚反应的产物分析

摘要

芳香胺改性双马来酰亚胺是双马来酰亚胺最主要的改性方法.本文通过凝胶渗透色谱、酸碱滴定、高效液相色谱等方法分析双马来酰亚胺(BDM)与4,4 '-二氨基二苯醚预聚(DDE)的反应物组成,推断产物结构式.结果表明,该条件下的BDM与DDE预聚反应,DDE绝大部分参加反应,BDM则显著剩余.产物中的伯胺主要来自DDE一端的伯胺与双马来酰亚胺的双键加成而另外一端没有加成的生成物.%Aromatic amine reaction with BDM is BDM major modification methods.This article has employed GPC ,titration and HPLC in analyzing the reaction product and infering the product structure. The results show that most of DDE was con-sumed in the reaction however BDM was superfluous observably. Primary amine in the product is mainly from the reaction that one side of DDE addition reaction with double bond of BDM but the other side of DDE without addition reaction.
