1. Numerical Simulation of Atom-Transfer Radical Polymerization of tert-butyl Methacrylate
Block copolymers based on tert-butyl methacrylate (tBMA) have many uses, such as thermo‐responsive polymers, amphiphilic copolymers, and many applications in the medical field. Atom-transfer radical polymerization (ATRP) is the main technique to produce these controlled macromolecular architectures. This paper provides a simplified kinetic modeling and com

2. Atom Transfer Radical Polymerization of Methyl Methacrylate Mediated by Grubbs 1st and 2nd Generation Catalysts: Insight into the Active Species
Ruthenium benzylidene complexes were evaluated as catalysts in atom-transfer radical polymerization (ATRP) of methyl methacrylate (MMA) under different reaction conditions. The mechanism by which Grubbs 1st and 2nd generation catalysts mediate olefin metathesis has been studied, little is known regarding the mechanism of ATRP reaction promoted by these compl

3. Simulation of temperature effect on the structure control of polystyrene obtained by atom-transfer radical polymerization
Abstract This paper uses a new kinetic modeling and simulations to analyse the effect of temperature on the polystyrene properties obtained by atom-transfer radical polymerization (ATRP). Differently from what has been traditionaly published in ATRP modeling works, it was considered “break” reactions in the mechanism aiming to reproduce the process at hi

4. Preparation of tunable wettability polymer (ionic liquid) brushes at rough substrate using surface initiated atom transfer radical polymerization
Através da técnica de polimerização radicalar por transferência atômica (ATRP) foram preparadas novos polímeros tipo pente com molhabilidade ajustável (líquido iônico) de hexafluorfosfato poli[2-(1-butilimidazolino-3-ila)etila metacrilato (PBIMH-PF6-), a partir de um substrato bruto modificado com uma camada iniciadora composta de brometo 2-bromois

5. Protein decorated Nanoparticules : Small Unilamellar Lipid Vesicules and Block Copolymers Micelles. / Nanoparticules Décorées par des Protéines : Vésicules Lipidiques Unilamellaires et Micelies à Base de Copolymères à Blocs
The formation of protein Annexin-A5 decorated (bio-functionalized) nanoparticles is of particular interest in micelle-mediated target drug delivery, in vivo magnetic resonance imaging, or controlled fabrication of biochips. This work describes an easy access to the synthesis and manipulation of block copolymer nano-objects exhibiting binding ability for the

6. Synthesis and Characterization of Silsesquioxane-Based Polymer Hybrids with Controlled Structure
We have developed a method to obtain polymer hybrids with control of inorganic content and molecular configuration. Hybrid poly(methyl methacrylate) (PMMA) was obtained via atom transfer radical polymerization (ATRP) initiated by octafunctional cubic silsesquioxanes using CuCl as catalyst. Two different ATRP initiators obtained by attaching specific chemical
