Structure, thermal and fracture mechanical properties of benzoxazine-modified amine-cured DGEBA epoxy resins

eXPRESS Polymer Letters, 2011
First, traditional diamine hardeners of epoxy resins (EP) were checked as potential accelerators for the benzoxazine (BOX) homopolymerization. It was established that the acceleration effect depends on both the type and amount of the diamine compounds ...
