The aim of this work is to synthesize a polyelectrolyte polymer (Polyvinyl alcohol (PVA)) through radical means and vinyl acetate as a vinylic monomer followed by hydrolysis. This includes its viscosity-mass which is well controlled. Its aim is also to optimize waste waters treatment of the purification station of the Galvacier Company (K
In this work we have synthesized a new bifunctional epoxy resin namely diglycidyl 3-aminopropyl triethylsilane (DGAPTES). This resin was synthesized in two steps: the first one is condensing the epichlorohydrin with 3-aminopropyl triethylsilane; the second is introducing the calcium carbonate as a base to form the oxirane cycle. The resin obtained was characterized by infrared Fourier transformation spectroscopy (FTIR), its chemical structure was also confirmed by the nuclear magnetic resonance of 1H and proton and carbon 13C (1H NMR and 13C NMR) on the one hand, and we have improved the thermal properties of the standard resin (DGEBA) by adding an amount of (DGAPTES) as an organic load in the standard matrix, on the other hand. This formulation has been studied by thermogravimetry as a macroscopic approach. The uptake of humidity of the standard DGAPTES and the crosslinked DGEBA/DGAPTES/MDA according to 80%/20%/traces was studied in order to improve the Fickien behavior.
In this study, we are interested in the development of a new model "Quantitative Structure Property Relationship" (QSPR). To illustrate the behavior inufigeant of the thermal degradation of resins oxides organophosphate based on the Quantitative Structure-Property Relationship (QSPR) and the quality of the experimental data. Subsequently, we have discussed the influence of the impact of the thermal parameters quantum chemistry on the retardant behavior of degradation of multifunctional resins (DGEBA, TGTEP, HGTEP and HGCP). Self-timer degradation prediction was made by the semi-empirical PM3 and DFT method database software Gaussian 03.
