Testo completoPoly(hydroxyalkanoate)s (PHAs) are biodegradable and biocompatible polyesters of interest for their application in the biomedical field or as alternative to plastics derived from the petroleum industry. The synthesis of PHAs by ring-opening polymerization (ROP) of cyclic monomers, β-lactones, enables a good control of the molar mass, the microstructure and the functionality of the polymers. The properties of the polyesters can be tuned by the using different monomers. In recent decades, various PHAs have been synthesized, in particular poly(hydroxybutyrate) (PHB) and poly(alkyl malolactonate)s (PMLARs). This work has been extended to the ROP a new family of β-lactones, namely 4-alkoxymethlylene-β-propiolatones (BPLORs). Thus, various yttrium-based catalyst systems provide (co)polymers with original tacticity (syndiotactic, atactic or isotactic) and topology (block, alternating or random copolymers). The stereoselectivity of the catalytic systems implemented is unprecedented in the current scientific context. Indeed, the nature of the substituants on the ancillary ligand of the yttrium complexes enables to tune the microstructure and therefore the properties of the resulting PHAs

Testo completoThe first chapter deals with the design of a new ligands library for the ethylene polymerization. A high throughput synthesis and screening approach is developed during this chapter to test a library of 2-iminobenzimidazole complexed on various late transition metals. This makes possible to draw conclusion on this type of ligands as well as for general polymerization important factors (temperature, pressure…) The second and the third chapters deal with the modification of bis-imine ligands by introducing a pyridyle group. This pyridyle group makes the ligands potentially N-alkylable, which changes the ligands and catalysts behaviours. The influence of the N-alkylation on those catalysts has been studied through NMR, FTIR and polymerization experiments. The last chapter is to make a method for the synthesis and the heterogeneous screening of unbridged métallocènes. The method has been applied on 36 catalysts

Testo completoBecause of its high melting point, high tensile strength, stiffness and chemical resistance, isotactic polypropylene has one of the leading and fast growing thermoplastic polymers in the world. However, commercial PPs usually have relatively low melt strength, which limits their use in applications such as blow molding. Since long-chain branching (LCB) is known to enhance the melt properties of a polymer, several approaches have been developed to make branched polypropylenes (electron beam irradiation, peroxide curing, grafting etc.). Development of metallocene technology provides unprecedented flexibility in polymer design. Many structural features, including LCB, can now be introduced into polymers. In this work, long chain branched isotactic polypropylene (LCB-iPP) was synthesized using {Cp'CR2Flu}ZrCl2 metallocene catalyst and fully characterized (rheological, spectroscopic and thermal analysis). The branching (macro-α-olefins having predominantly vinyl-terminated chain end) was in situ generated and further incorporated by the same catalyst system to obtain LCB-PP/Linear PP blends. The LCB content was increased using a novel tandem catalysts system for converting propylene alone to isotactic polypropylene with long branches which exhibit enhanced melt properties

Testo completoThe works in this memory describes the carbone-carbone coupling: the first part is the synthesis of new olefin polymerization catalysts. The second one is the study of the influence of supports for the Kharasch reaction. In the first research way, three studies are presented: the study of a library of deprotonated oxime ligands, the study of a library of ligands with a ferrocene and a new methodology for the screening of catalysts for the 1-hexene polymerization. These works show the discovery of an active system for the ethylene polymerization. The last part is the optimization of the Kharasch reaction for an application with a reagent flow. This application may be possible with the use of a support like SBA and with microwave assistance. The complete conversion is obtained after one minute for the best conditions
