Multiple Controlled Graft Copolymers by Transition Metal-Catalyzed Living Radical Polymerization

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...

Block and Graft Copolymerization by Controlled/Living Radical Polymerization Methods

Recent developments in metal-catalyzed living radical polymerization

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...

Photoinitl&tion of Free-radical Polymerization by Transition Metal Derivatives

Two types of photoinitiator are considered: (1) transition metal complexes (mainly carbonyls), (2) chelates of transition metals. In systems of type (1) the metal is in a low oxidation state and an organic halide is generally, but not always, present; on thc other hand, in (2) the metal is initially in a high oxidation state. Comparison between photoand thermal-initiation is made for each type....
