Living Radical Polymerization: a Review

Free radical polymerization is one of the most widely employed polymerization techniques. This technique is applied to prepare latexes to be used in paints, high molecular weight poly (methyl methacrylate) for safety glass (Plexiglas), or foamed poly (styrene) to be applied in coffee cups. Some advantages of radical polymerizations, with respect to other techniques, are the relative insensitivi...

Block and Graft Copolymerization by Controlled/Living Radical Polymerization Methods

Living Radical Polymerization via Organic Superbase Catalysis

Organic superbases reacted with alkyl iodides (R–I) to reversibly generate the corresponding alkyl radicals (R). Via this reaction, organic superbases were utilized as new and highly efficient organic catalysts in living radical polymerization. The superbase catalysts included guanidines, aminophosphines and phosphazenes. Low-polydispersity polymers (Mw/Mn = 1.1–1.4) were obtained up to high co...

Preparation of Reactive and Thermal Stable Hyperbranched Graft Copolymers/ Clay Nanocomposite via ‘Living’ Free Radical Polymerization

Exfoliated poly (Chloromethyl styrene-co-styrene)-g-polyacrylonitryle/organo- modified montmorillonite [P(CMSt-co-St)-g-PAN/O-MMT] nanocomposite was synthesized through solution intercalation method by using atom transfer and nitroxide mediated radical polymerization. At first, poly (chloromethyl styrene-costyrene) copolymer was synthesized by nitroxide - mediated “living” free radical polyme...

Improving photo-controlled living radical polymerization from trithiocarbonates through the use of continuous-flow techniques.

Herein, we report simple flow reactor designs that enable photo-controlled living radical polymerization (photo-CRP) from trithiocarbonates (TTCs) with significant enhancements in scalability and reaction rates compared to the analogous batch reactions. We also demonstrate the "on/off" photo-switchability of this reaction under flow conditions.
