Synthesis and Microscopic Characterization Of The Urea Macromolecule Tetraglycidyl Ether Of Bisphenol A (TGEUBA) : Optimizating The Parameters By The Experimental Design And The Formulation of A Nanocomposite By Trisodium Phosphate And TGEMDA.

Abstract

The main objective of our work is to synthesize the standard matrix and formulate it by the tri-sodium phosphate: Urea tetraglycidyl ether of Bisphenol A (TGEUBA). We obtained the precursor molecule of the epoxy matrix Urea tetrabisphénol A (Utba) and then we tended towards the functionalization of the latter with epichlorohydrin. Microscopic characterization of the TGEUBA resin was obtained by using the Fourier Transform Infrared (FTIR) and was confirmed by the nuclear magnetic resonance (NMR). The dispersion power of the tri-sodium phosphate in the presence of an adjuvant in the TGEMDA TGEUBA prepolymer crosslinked and formulated at different percentages (0%, 10% PTS TGEMDA 10% and 10% TSP + 10% TGEMDA) was followed up by using the Scanning Electron Microscope (SEM). Moreover, we have optimized the synthesis with the erection of the TGEUBA by the method of experimental design (Nimrod W).
