Poly(methyl methacrylate) grafted imogolite clay nanotubes were fabricated via activators regenerated by electron transfer for atom transfer radical polymerization (ARGET ATRP) by designing a water-soluble amphiphilic ATRP initiator that can adsorb onto imogolite surface in an aqueous solution.

This work investigates the interactions of a polycationic nanocarrier with siRNA and with cells in order to better understand the capabilities and limitations of the carrier. The polycationic nanocarriers are cross-linked copolymer nanoparticles synthesized in a single-step reaction using ARGET ATRP (activators regenerated by electron transfer atom transfer radical polymerization). The polycati...

This communication describes the first example of the efficient use of a simple amphiphilic molecule as both a surfactant and an initiator in the miniemulsion polymerization of methyl methacrylate under AGET and ARGET ATRP conditions.

Conventional synthesis of polymers by ATRP is relatively low throughput, involving iterative optimization of conditions in an inert atmosphere. Automated, high-throughput controlled radical polymerization was developed to accelerate catalyst optimization and production of disulfide-functionalized polymers without the need of an inert gas. Using ARGET ATRP, polymerization conditions were rapidly...

The grafting of poly(hydroxyethylmethacrylate) on polymeric porous membranes via atom transfer radical polymerization (ATRP) and subsequent modification with a photo-responsive spiropyran derivative is described. This method leads to photo-responsive membranes with desirable properties such as light-controlled permeability changes, exceptional photo-stability and repeatability of the photo-resp...

The synthesis of polymer brush decorated silica nano-particles is demonstrated by activator regeneration by electron transfer atom transfer radical polymerization (ARGET ATRP) grafting of poly(tert-butyl methacrylate). ATRP initiator decorated silica nano-particles were obtained using a novel trimethylsiloxane derivatised ATRP initiator obtained by click chemistry. Comparison of de-grafted poly...

Activators regenerated by electron transfer (ARGET) atom radical polymerization (ATRP)-based aqueous miniemulsion where the takes place in stabilized monomer droplets is described. In this work, we compared styrene, n-butyl methacrylate (nBMA) and tert-butyl (tBMA) investigated influence of their hydrophobicity on dispersity, molecular weight particle stability based partition coefficients (log...

The first example of activators regenerated by electron transfer atom radical polymerisation (ARGET ATRP) under precipitation (PP) conditions is reported. This new method for polymer synthesis (called ARGET ATRPP) requires only very low levels metal catalyst success, a distinctive feature that enables the production uniform microspheres reversible-deactivation control. influence (monomer concen...
