Study on the Reaction Mechanism of Epoxy Resin/Dicyanamide System

Department of Chemistry, The State Key Laboratory of Functional Polymer Materials for Adsorption and Separation, Nankai University, Tianjin 300071

Received Date: 26 September 1997
Revised Date: 12 January 1998

The reaction mechanism, reactivities, and apparent activation energies of epoxy/dicyanamide curing system accelerated by C₆H₅NHCONR₂ (R=CH₃, n-C₄H₉, i-C₃H₇) were studied by DSC and GC techniques. The results showed that in reaction of C₆H₅,NHCONR₂ with either dicyanamide or epoxy resin there was a dimethylamine released reacting with epoxy resin, giving a tertiary amine, which accelerated the anionic homopolymerization of epoxy resin.
