Synthesis and identification of polystyrene via conventional and controlled radical polymerization methods: Effect of temperature, initiator and transfer agent on molecular weight and reaction rate
Polystyrene (PSt) has been known as one of the important polymers with a wide range of applications. Ability to synthesize PSt with different but predictable molecular weights for various applications is very important in the laboratories and industries. In this study, using various simple and inexpensive techniques with only free radical mechanism, it was tried to synthesize PSt with different...
متن کاملThioketone spin traps as mediating agents for free radical polymerization processes.
Thioketones are demonstrated to be suitable agents for controlling free radical polymerization processes: the polymerizations carry (pseudo) living characteristics indicating that the control process is induced by a persistent radical effect.
متن کاملSurface Modification by Chemically Grafted Initiators
To modify the surface properties of inorganic materials, we successfully covalently attached a stable monolayer, with high grafting density, of N,N(diethyl)dithiocarbamoylbenzyl(trimethoxy)silane on the surface of silicon wafers and glass substrates, thereby creating a surface-grafted photoinitiator for “living” free radical photopolymerization. The surface-grafted initiators were utilized for ...
متن کاملVarious radical polymerizations of glycerol-based monomers -Review-
This review aims at making the state of the art of the radical polymerizations of glycerol-based monomers, especially (meth)acrylate and vinylic/allylic derivatives. Acrylate and methacrylate derivatives bearing numerous secondary groups like ester, cyclocarbonate, acetal and urethane were involved in free radical polymerization and radical controlled polymerizations as well as in the photopoly...
متن کاملPreparation 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...
