The invention provides N-cyanoethylated toluenediamines (CNTDAs), processes for synthesizing them, and compositions containing them. In preferred embodiments, the CNTDAs are represented by the following formula:
where the nitrogen atoms are ortho or meta to each other on the aromatic ring. The CNTDAs are particularly suitable for use as latent curing agents for epoxy resins.
本发明提供了 N-氰乙基化甲苯二胺(CNTDAs)、合成它们的工艺以及含有它们的组合物。在优选的实施方案中,CNTDAs 由下式表示:
其中氮原子在芳香环上相互正交或偏交。CNTDA 特别适合用作环氧树脂的潜在固化剂。
