“…Recently, the research developed in the field of epoxy polymer aims to replace bisphenol A with a precursor without degrading the physical and chemical properties [23, 24]. In this paper, we presented the synthesis of a new epoxy polymer from a reagent containing four mobile hydrogen atoms such as methylene dianiline (MDA) with phosphorus pentachloride (PCl 5 ) [25].…”

Epoxy polymer, namely, decaglycidyl pentamethylene dianiline of phosphorus (DGPMDAP) was synthesized in three steps. The synthesis of epoxy polymer DGPMDAP was investigated by nuclear magnetic resonance spectroscopy, rheological analysis, scanning electron microscope (SEM), stationary and transient electrochemical methods (PDP and EIS), respectively. The rheological properties of composite (DGPMDAP/MDA/TiO2) without and with different percentages of titanium dioxide (0%, 5%, 10% and 15%) increase with both the increase in frequency and with rate of load of titanium dioxide. Besides, SEM micrographs shows a good dispersion of the titanium dioxide charge in the composite (DGPMDAP/MDA/TiO2) elaborated. The results of PDP show that epoxy polymer DGPMDAP acts as mixed type inhibitor and reaches maximum corrosion inhibition efficiency reaches 92 % at 10−3 M. Besides, EIS results indicate that DGPMDAP act as good inhibitor for carbon steel in 1 M HCl solution and its efficiency reaches 91 % at 10−3 M of DGPMDAP. Furthermore, the adsorption of DGPMDAP on carbon steel surface obeyed Langmuir isotherm.

“…The synthesis of the epoxy resin named pentaglycidyl ether pentabisphenol A of phosphorus (PGEPBAP) was carried out in two steps according to Hsissou et al [9]. The first step consists of condensing 0.004 mol of phosphorus pentachloride with 0.026 mol of bisphenol A in the presence of the 4.274 mol of methanol with magnetic stirring for 48 h at 100 °C.…”

“…The polyepoxide architecture can be converted into a thermosetting matrix via the methylene dianiline acting as a hardener during the implementation. Methylene dianiline has a very good thermal stability and lends very good mechanical properties to the pre-polymerized resin (epoxide + hardener) [9] this is why they are often used for high-tech applications. Methylene dianiline are bearing two amine functions among which the four hydrogens can be substituted.…”

“…We hardened the pentafunctional epoxy resin; pentaglycidyl ether pentabisphenol A of phosphorus (PGEPBAP) in the presence of methylene dianiline as a hardener at approximately stoichiometric amounts [9]. The equivalent epoxy weight (EEW) and the amine hydrogen equivalent weight (AHEW) are calculated according to Eqs.…”

Novel pentafunctional epoxy resin, mainly based on pentaglycidyl ether pentabisphenol A of phosphorus (PGEPBAP) has been synthesized and characterized through different spectroscopic methods (FTIR, 1 H NMR, 13 C NMR and 31 P NMR). Moreover, the analysis of the viscosity of (PGEPBAP/Methanol) system was determined by using viscosimeter VB-1423 of the Ubbelohde type. Furthermore, the analysis of the rheological properties of the matrix PGEPBAP and their (PGEPBAP/ MDA/PN) elaborated composite was performed according the RHM01-RD HAAKE rheometer. In addition, the morphology of different (PGEPBAP/MDA/PN) prepared composite was determined by using the polarizing optical microscope.
