Résines époxydes—2 Mécanisme réactionnel et cinétique de la réaction du diglycidyl amino-1-méthyl-2-benzène sur les amines aromatiques

The study of the polyaddition of diglycidyl-1-amino-2-methyl benzene (commercial grade and purified in the presence of primary, secondary and tertiary aminobenzenes) by HPLC, chemical measurements, high resolution NMR in the solid (CP MAS) and liquid (¹³C and ¹⁵N) states has allowed the reactivity of the N(epoxy)-2 group to be determined and a reaction mechanism to be proposed. Comparison of results obtained for the commercial grade and purified resins shows the role of impurities on reaction kinetics and on the structure of the final polymer network.
