Abstract:
Photoinduced atom transfer radical polymerization (ATRP) was achieved using a simple household fluorescent lamp as the light source. In solution, methyl methacrylate could be polymerized to welldefined polymers; the photoinduced ATRP system did only convert monomers during irradiation and was inactive in the dark. In situ monitoring by UV-vis spectroscopy revealed the photoredox cycle between Cuᶦᶦ and Cuᶦ species. The linear development of the polymer number average molar mass with monomer conversion, the low dispersity as well as chain extension experiments showed the controlled nature of the

Abstract:
Sherrington and co-workers have shown that branched vinyl polymers can be synthesized by the addition of a chain transfer agent to a conventional free radical statistical copolymerisation of a vinyl and a divinyl monomer. In the presence of the chain transfer agent, the molecular weight of the primary chains is reduced, gelation can be suppressed and soluble, branched polymers are obtained as the sole product. Living polymerisation techniques offer a way to control the primary chain length without the need for a transfer agent simply by adjusting the monomer/initiator molar ratio. It is sugges

Von der Natur geschaffene Polymere faszinieren Polymerforscher durch ihre spezielle auf eine bestimmte Aufgabe ausgerichtete Funktionalität. Diese ergibt sich aus ihrer Bausteinabfolge uber die Ausbildung von Uberstrukturen. Dazu zählen zum Beispiel Proteine (Eiweiße), aus deren Gestalt sich wichtige Eigenschaften ergeben. Diese Struktureigenschaftsbeziehung gilt ebenso für funktionelle synthetische Makromoleküle. Demzufolge kann die Kontrolle der Monomersequenz in Polymeren bedeutend für die resultierende Form des Polymermoleküls sein. Obwohl die Synthese von synthetischen Polymeren mit der

Abstract:
L’objectif était de développer et d’utiliser des nanoparticules hybrides de type«coeur-écorce» composées d’un coeur de silice dense entouré par des chaînes polymères fonctionnalisées par des ligands d’ATRP comme support catalytique pour la polymérisation du MMA par ATRP. Deux stratégies de synthèse de nanoparticules hybrides ont été élaborées. La première a consisté à immobiliser sur un support de silice, d’une manière covalente, des chaînes fonctionnelles synthétisées par NMP comportant des ligands capables de complexer le bromure de cuivre. Des nanoparticules de SiO2@polymère fonctionnel aya

Abstract:
The use of living radical polymerization methods has shown significant potential to control grafting of polymers from inert polymeric substrates. The objective of this thesis is to create advanced substrates for use in combinatorial chemistry applications through the use of g-radiation as a radical source, and the use of RAFT, ATRP and RATRP living radical techniques to control grafting polymerization. The substrates grafted were polypropylene SynPhase lanterns from Mimotopes and are intended to be used as supports for combinatorial chemistry. ATRP was used to graft polymers to SynPhase lante

Abstract:
Controlled radical polymerizations (CRPs) are among the most powerful methods to obtain polymers with well-defined properties and high commercial value. Atom transfer radical polymerization (ATRP) is probably the most widely used CRP, in academia and industry, thanks to its versatility and simplicity. In ATRP, a metal complex in a low oxidation state, MtzLm (typically a copper-amine system, [CuIL]+) reacts with a dormant polymeric chain Pn–X (where X = Cl, Br) to produce radicals Pn• that can propagate, in the bulk of the solution, by addition to monomer units. In this reaction, the copper com
