Light-controlled, living radical polymerisation mediated by fluorophore-conjugated RAFT agents

Organotellurium-mediated living radical polymerization under photoirradiation by a low-intensity light-emitting diode

A low-intensity (6 W) light-emitting diode (LED) effectively activated an organotellurium chain transfer agent and the dormant species, promoting well-controlled radical polymerization. The use of the LED provided many advantages over the previously reported high-intensity Hg lamp, including high energy efficiency during the polymerization, and easy availability of the low-cost light source.

Controlled radical polymerisation of methyl acrylate initiated by a well-defined cobalt alkyl complex.

Cobalt-mediated radical polymerisation of methyl acrylate is effected at moderate temperature by both a square planar bis(beta-ketoaminato)cobalt(II) complex in the presence of V-70 diazo radical initiator, and by a well-defined cobalt(III) alkyl derivative in the absence of a diazo complex. Polymerisation rates suggest that both reversible termination and degenerative transfer mechanisms are o...

Block and Graft Copolymerization by Controlled/Living Radical Polymerization Methods

Chapter I: Controlled/”living” Free Radical Polymerizations

One-pot tandem living radical polymerisation-Huisgens cycloaddition process ("click") catalysed by N-alkyl-2-pyridylmethanimine/Cu(I)Br complexes.

Azide terminally functional poly(methyl methacrylate)s (Mn = 4000-6000, PDI = 1.21-1.28) have been prepared by living radical polymerization and successfully reacted with alkynes in a Huisgen cycloaddition (click) reaction in one pot using the same catalyst for both processes.
