This invention provides methods for controlled single electron transfer living radical polymerization (SET-LRP) of monomers with increased conversion, high molecular weights and low polydispersity by allowing the polymerization to proceed at low temperatures via a tubular reactor either made of copper or containing copper metal surface.
摘要:
L'invention concerne un copolymère à blocs amphiphile comportant au moins un premier bloc hydrophile susceptible d'être obtenu à partir de monomères d'acrylate de n-butyle et de méthacrylate d'hydroxyéthyle, et un deuxième bloc hydrophobe susceptible d'être obtenu à partir d'un monomère de méthacrylate de méthyle. Ce copolymère s'avère particulièrement avantageux pour une utilisation en tant qu'additif pour la fabrication d'une membrane polymère de filtration, notamment à base de PVDF, en particulier par un procédé d'inversion de phase.

摘要:
Composite hydrogels with a chiral organization with tunable responsive photonic properties are conceived. A polymerizable hydrophilic monomer such as acrylamide is reacted in the presence of nanocrystalline cellulose (NCC) to give a composite hydrogel with cellulose nanocrystals embedded in a chiral nematic organization. Through control of the reaction conditions, the hydrogel can exhibit photonic colour that can be varied throughout the visible and near-infrared regions. The colour shifts substantially and reversibly upon swelling and shrinking of the hydrogel through solvation in aqueous and nonaqueous media. The responsive properties can be tailored both through choice of monomer and/or through chemical modification of the NCC surface. Examples of possible applications of the materials are: tunable reflective filters, chemical sensors, stationary phases for electrophoresis of chiral or achiral substances, and as a template to generate new materials with chiral nematic structures.
