This review presents a short overview of recent developments in metal-catalyzed living radical polymerization, mainly focusing on our recent research studies related to the subject. Metal-catalyzed living radical polymerization or atom transfer radical polymerization, which was originally developed via evolution of the metal-catalyzed Kharasch or atom transfer radical addition to chain-growth p...

In the present work, well ordered, mesoporous carbon nitride (MCN) sorbent with uniform mesoporous wall, high surface area and pore volume has been fabricated using the simple polymerization reaction between ethylene diamine and carbon tetrachloride in mesoporous silica media, and then modified by TiO2 nanoparticles (Ti-MCN). The structural order and textural properties of the nanoporous materi...

The design of reactive species that can either serve to initiate the ring-opening polymerization epoxides for synthesis high molar mass polyethers or be alternatively used catalyze polyether telechelics in presence chain transfer agents has long been an elusive goal. Here, we report a series bifunctional borinane-based catalysts enable living with unprecedented activity (TOF ? 1.8 × 105 h–1) an...
