Elaboration of new epoxy resin octafonctionnelle by chemical modification of the DGEBA. Study of the rheologic parameter

Abstract

The objective of our work is to synthesize a new octafunctional epoxy resin in two steps. In the first step we obtained the DGEBA with bisphenol A. The second step, leading to the synthesis of an octafunctional resin by the action of a nucleophile on the DGEBA is not evident by the conventional route. The latter would require several steps with various monomers certainly low. Firstly, microscopic characterization was obtained by using the Fourier Transform Infrared (FTIR), and nuclear magnetic resonance (NMR) 1 H and 13C. The characterization of this new viscosimetric octafunctional resin was evaluated on the other hand.
