N-cyanoethylated ortho and meta toluenediamine compositions and process for making them

Abstract

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: 1 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.
