Full textIn this manuscript we study telechelic associative polymers (APs) composed of hydrophilic poly(ethylene oxide) chain (PEO, Mn = 20 000 g/mol) end-capped by hydrophobic groups. Symmetric APs have the same hydrophobic group at each end and asymmetric APs contain an alkyl group on one chain end and a perfluoroalkyl group on the other one. The aim of this work was to establish a relationship between the microscopic structure and the rheological properties of APs in aqueous solution. The asymmetric AP synthesis is carried out by anionic polymerization of ethylene oxide initiated by an hydrocarbon alkoxide, followed by esterification with a perfluoroalkylated carboxylic acid. By this way we can obtain completely end-capped APs with a low polydispersity index. Polymers are purified using a molecularly imprinted polymer MIP. In aqueous solution, APs form aggregates and can lead to a phase separation. To investigate homogeneous solutions a surfactant is added: the sodium dodecyl sulfate (SDS) or the lithium perfluorooctyl sulfonate (LFOS). The dilute solution studies in the presence of SDS, by tensiometry, 13C NMR and SANS, enable to determine the aggregate structure as a function of concentrations of the two components. In semi-diluted solution, APs form a transient network with an increase of viscosity. The aqueous solution study by rheology reveals correlations between the AP chemical structure (hydrophobic group length and nature, symmetric or asymmetric AP) and the network rheological characteristics (relaxation time t and elastic modulus G0). The SDS influence is compared with that of the perfluorinated surfactant LFOS

Full textThe rheological behavior of polymer melts in microscale geometries is not really understood yet. In such processes which involve gaps thinner than 100µm (e.g. micro-injection molding), the material behaves differently compared to macroscopic flows. Besides, most polymer processing techniques involve pressure flows and only very few studies can be found about pressure flows in such thin geometries. The aim of this study was, first, to develop an experimental method which can provide relevant data about the rheological behavior of polymer melts in pressure flow taking place in microscale geometries. In order to get better descriptions of the physics involved in such flows, numerical simulation with commercial and home-made softwares was also implemented, especially with molecular dynamics constitutive models. Thus, a modular rheometrical slit die equipped with pressure and temperature transducers was designed to be adapted to a capillary rheometer, with different gap dimensions available, between 50µm and 200µm. The device was assessed by comparing to usual rheological ones, and wall slip was investigated according to Mooney’s method. Then, simulation of the flow was performed with POLYFLOW®. The pressure effect on the geometry and on the polymer material was investigated. Besides, simulation was also conducted with MATLAB® by implementing the Doi-Edwards’ tube model (reptation theory) and the Molecular Stress Function concept of Wagner to take into account the enhanced orientation of the molecules due to the very close vicinity of the die walls. Experimental results were compared to calculations, and the discussion of the discrepancies was supported by POLYFLOW® simulations. The conclusions somewhat modify the prospects for future studies of such flows

Full textThe work of this thesis concern the synthesis and the study of acrylic copolymer reticulate in a physical way (associative polymer HASE) or in a chemical way (non-associative polymer ASE). The main objective was to bring a better comprehension of the sensitivities of this type of polymer in specific matrix ; aqueous solutions containing a strong concentration in surface-active agent and/or electrolyte. The studies on polymers known as associative consisted on the synthesis of acrylic polymers with "combs" structure having hydrophobic side chains. This type of polymer has the capacity to reticulate physically due to an auto-association of hydrophobic segments. There is formation within the aqueous solution of structures calls hydrophobic junctions. Paradoxically, these hydrophobic junctions which give the strong rheological properties of associative polymers involve a strong sensitivity to the amphiphilic surfactant. Introduction of surfactant seems to destabilize the set of hydrophobic junctions and involve a significant loss of cohesion inter-chains of polymer. It thus was set up the associative polymer synthesis having of the fluorinated segments present on the macro-skeleton or the side chains in order to minimize the interactions polymer/surfactant. The studies on polymers known as non-associative consisted of an optimization of an industrial system, the polymers ASE (Akali-Soluble Emulsion), in order to increase the general properties of this type of polymer. With through the introduction of various crosslinking agents into the acrylic copolymer of the type MA-EA, we evaluated the importance of the characteristics of these additives on the rheological properties of polymers in solution. The addition of encumbered monomers of type isobornyle methacrylate in the structure of polymers was also planned in order to decrease "the effect of salt" which translates the strong sensitivity of this type of polymer to the electrolytes. Thus, the studies concerning acrylic copolymers containing a short reticulant and a doping with a monomer isobornyl, led to a structure of the type ASE having better rheological performances that the reference reported on our industrial partner
