Повний текст джерелаThis present thesis deals with the development of active olefin polymerization catalysts based on late transition metal (nickel and iron) imino-pyridine complexes supported on nanomaterial. Chapter I gives a comprehensive literature review of unsupported and supported ethylene polymerization catalyst. In Chapter II we report the ethylene polymerization studies using nickel complexes containing an –NH2 group for covalent immobilization on multi-walled carbon nanotubes (MWCNTs) of the corresponding precatalysts. Comparison of the homogeneous catalysts with their supported counterparts evidenced higher catalytic activity and higher molecular weights for the polymers produced. In Chapter III, iron complexes containing a pyrene group have been synthesized and immobilized on MWCNTs through non-covalent π-π interactions between pyrene group and surface of MWCNTs. Activated by MMAO, both the iron complexes and immobilized catalysts show high activities for ethylene polymerization. It was possible to evidence that MWCNTs have a great influence on the catalytic activity and on the structure of the resulting polyethylenes. Imino-pyridine nickel complexes containing various kinds of aromatic groups have been synthesized in Chapter IV and polymerization conditions in the presence and in the absence of nanocarbon materials, such as MWCNTs or few layer graphene (FLG), are discussed. For those nickel catalysts bearing 1-aryliminoethylpyridine ligands, the presence of MWCNTs in the catalytic mixture allows the formation of waxes of lower molecular weight and polydispersity, whereas the presence of FLG proved to be beneficial for the catalytic activity. In Chapter V, isoprene polymerization catalyzed by iron complexes containing polyaromatic groups and non-covalently supported on nanoparticles and confined into the inner cavity of MWCNTs (Cat@NPs and Cat@NPs@MWCNTs) are investigated. Iron complexes show excellent activity for the isoprene polymerization and produced high glass temperature polyisoprene with a high trans-1,4-polyisoprene selectivity. Polymer nanocomposites are produced by supported catalysts and, transmission electron microscopy (TEM) evidenced efficient coating of the resulting polyisoprene around the oxygen sensitive iron nanoparticles

Повний текст джерелаThe aim of this project is to develop hybrid nanoparticles bearing well definedpolymer arms as supported catalyst for the atom transfer radical polymerization of methylmethacrylate. This new generation of “semi heterogeneous" catalysts was prepared by twostrategies. The first consisted of immobilizing the polymer arms bearing the ligands enablingcoordination of copper bromide onto silica particles by covalent bonds. Hybrid nanoparticleswith low polymer grafting density were targeted to prevent the overlapping of chains on thesurface. Unfortunately, the polymerizations were not controlled probably due to a lack ofaccessibility of the initiator and propagating radicals to the copper complexes. To improve theaccessibility, a reversibly supported catalyst was developed via self-assembly using hydrogenbonding between chains α-functionalized by a proton donor-acceptor unit (DAD) and acomplementary unit (ADA) anchored on silica particles. These new hybrid materials wereefficient in the controlled radical polymerization of MMA, yielding polymers with controlledmolecular weights and dispersities narrower than those obtained for homogeneous ATRP.Moreover, after catalyst separation from the reaction medium by centrifugation, more than96% of the originally used copper was recovered

Повний текст джерелаThe aim of our project was to develop an eco-friendly process based on heterogeneous asymmetric organocataysis in continuous flow conditions. To succeed in this development, we chose to use a quinine-derived bifunctional organocatalyst: cupreine. Silica, a mesoporous inorganic material, was chosen as the support to immobilize this organocatalyst. The grafted cupreine was then tested as catalyst for the asymmetric Michael addition between the trans-β-nitrostyrene (Michael acceptor) and the dimethyl malonate (Michael donor) in continuous flow condition.First, we immobilized the catalyst on two types of silica, following three different strategies. The various cupreine-grafted silicas we obtained were functionnalized with 0.2 to 0.4 mmol of cuprein per gram of silica. Each one of them possessed specific characteristics depending of the followed strategy.The assessment of the catalytic activity of immobilized silica was then performed in batch condition. Different bio-based solvents were used for the Michael addition. 2-MeTHF was chosen as the best solvent among those tested and used in continuous flow. Immobilized cupreine proved to be as efficient in heterogenous condition as in homogenous (enantiomeric excess was superior or equal to 85 % and conversion better than 96 %), except for turn over frequency (TOF, mol of converted substrate/mol of catalyst/reaction time) which is three times lower in hetereogeneous condition (0.2h-1 to 0.6 h-1 in homogenous condition).Michael addition of trans-β-nitrostyrene to dimethyl malonate was then realized in continuous flow condition, using the various silica-supported catalysts. Turn over frequency of cupreine was doubled (0.4 h-1) and the turn over number (mol of converted substrate/mol of catalyst) increased from 16 to 63 in continuous flow condition. Derivatives of trans-β-nitrostyrene (chlorinated, phenolic and methoxylated in position 4) were successfully tested in continuous flow.To the best of our knowledge, we realized the first asymmetric Michael addition between trans-β-nitrostyrene and the dimethyl malonate, catalysed by silica-supported cupreine in batch and in continuous flow, using a bio-based solvent.We successfully developed an eco-friendly process based on heterogeneous organocatalysis in continuous flow. This process favorited an efficient recycling of the supported catalyst, and increased the productivity of grafted cupreine compare to the heterogeneous condition in batch. The enantioselectivity of the cupreine for this reaction was similar in both homogeneous and heterogeneous conditions

Повний текст джерелаThis work deals with the development of new ways of immobilization of ionic liquids in polymer matrices. Three ways of immobilization were tested. In the first one, the ionic liquid was encapsulated in polyelectrolyte microcapsules. In the second one, the combination of Pickering emulsion and layer by layer techniques were tested to immobilize ionic liquid. Finally, in the third one, the ionic liquid was entrapped in biopolymer matrices. For the first way, the study of the stability of polyelectrolyte microcapsules in ionic liquid showed that a cross-linking step was necessary to get stable microcapsules in this ionic media. The cross-linked microcapsules were used as microreactors for the synthesis of PMMA, a hydrophobic polymer, in ionic liquid media. Then, microcapsules containing ionic liquid were prepared and applied to metallic depollution. The second way based on the combination of Pickering emulsion and the layer by layer techniques was unsuccessfully applied to the emulsion “ionic liquid in water” and did not allow the immobilization of the ionic liquid phase. In the third way, ionic liquid immobilization proceeded by confinement of an ionic liquid phase in chitosan or alginate beads. The prior solubilisation of an organometallic catalyst in the ionic liquid phase led to catalytic materials which were tested with the Tsuji-Trost reaction
