This paper summarizes a review of the viscosimetric, viscoelastic and rheological properties of polymers and hybrid nanocomposite polymers. Hybrid nanocomposites can be combined from natural fibers or synthetic fibers and/or both. The hybrid nanocomposite polymer offers the designer the opportunity to achieve the required characteristics to a considerable extent controlled by the choice of appropriate fibers or fillers and the polymer architecture. The rheological behavior of hybrid nanocomposite depends on fiber content, fiber length, fiber orientation, fiber-to-matrix bonding, fiber configuration and filler, respectively. Further, rheological properties of hybrid nanocomposite polymers by introducing various charges were examined discussed.

The objective of our work is to study, develop, characterize and apply a new epoxy macromolecular matrix in coatings, and their optimization for the conservation of marine heritage. Epoxy resins are technologically and nano-technologically compatible thermosetting macromolecule matrices that are easy to implement, according to their structures, viscosimetric and rheological properties, for the protection of the heritage possibly subject to atmospheric corrosion. In this sense, we have tested the new macromolecular binder, hexaglycidyl ethylene of methylene dianiline (HGEMDA), crosslinked and formulated for studying the behavior of steel coatings in a marine environment. In order to evaluate HGEMDA coating performance, we have studied its adsorption behavior onto the surface of corroded steel, and explained the interactions between the coating macromolecule and the steel surface. The coating effect on E24 steel was studied by quantum chemical calculations. The adsorption of HGEMDA onto the surface of E24 steel has been well described by the Quantitative Structure of Relation Property model (QSPR). The stationary and transient electrochemical studies are very interesting, since the prediction of the coating behavior was performed by the semi-empirical PM6, DFT methods and the method of three Becke compounds of parameter (UB3LYP), based on 6-311 G. All our calculations were performed using Gaussian software (03).

The aim of our work is to synthesize a new phosphorus tri-functional epoxy resin tri-glycidyl ether tri-mercaptoethanol of phosphorus (TGETMEP) in two stages. In the first stage, we got the precursor molecule of the epoxy matrix tri-mercaptoethanol phosphate (METR). The second step led us to the synthesis of tri-functional resin TMEP condensation with epichlorohydrin. The standard TGETMEP resin was characterized by the Fourier infrared transformation (FTIR) and nuclear magnetic resonance (NMR), on one hand. The viscosimetric analysis was investigated by the Hebbelod capillary viscometer and rheometer Rheomat 01, on the other hand. The cross-linked resins and tertiary formulated composites have been studied by the rheometer 01 which was observed by means of SEM.

During this paper, we improved the compressive strength of cementitious matrix based on ion exchanging resin (IER) at 12% and formulated by the modified novolac epoxy polymer surfactant (NEPS) at various percentages (0, 1, 2, 3, 4 and 5%). The results show that the introduction of 1% and 2% of NEPS in the cementitious matrix with 12% of IER increases the compressive strength compared to that of the basic matrix (from 7 to 90 days). However, the formulations 3, 4 and 5% show the compressive strength is less than that of the basic matrix (from 28 to 90 days). Epoxy polymers cover various industrial areas such as: electronics, coating, inhibition, space construction and radioactive waste 1-5. Epoxy polymers have many properties, including viscosimetric, thermal, morphological, rheological and mechanical compressive of strength 6-9. At this time, the most widely employed process for the synthesis of epoxy polymers is the condensation of epichlorohydrin on structures having at least two mobile hydrogen atoms such as diamines, diacids and polyphenols. Also, the oxidation of polyunsaturated compounds and/or the condensation of glycidol with halogenated compounds 10,11. Novolac epoxy polymers are obtained by the condensation of phenol with formaldehyde in an acid medium 12,13. The objective of this paper is to improve the chemical compressive of strength of the cementitious matrix based on ion exchanging resin (IER) at 12% formulated by novolac epoxy polymer surfactant (NEPS) modified at various percentages (1, 2, 3, 4 and 5%) 14-16. We have studied the properties of mechanical of compressive strength, varying the polymer amounts incorporated in cementitious matrix formulations. This gave us the reflection to introduce the modified novolac epoxy polymer in surfactant form into the cementitious matrix. Besides, the results obtained show an increase in mechanical compressive of strength after 7, 14, 28 and 90 days of confinement compared to the basic matrix. Material and Methods Ion exchange resin (IER). Ion exchange resin is a crosslinked macromolecular water insoluble matrix which, upon contact with a solution, can exchange the ions it contains with other ions of the same sign from the solution used in water purification of the reactor vessel Mark TRIGA II 16. Their physicochemical properties are shown in Table 1. Novolac epoxy polymer (NEP). Epoxies are excellent matrices of high performance polymers. The latter are synthesized by polycondensation reaction and are used in several fields such as conditioning of radioactive
