  • Continuous flow homogeneous alkene metathesis with built-in catalyst separation
    Green Chemistry, 2011
    Co-Authors: Rubén Duque, Frédéric Caijo, Marc Mauduit, Eva Oechsner, Hervé Clavier, Steven P. Nolan, David Cole-hamilton
    Abstract:

    Continuous flow homogeneous alkene metathesis using a supported ionic liquid phase (SILP) catalyst with CO2 as a transport vector allows the self-metathesis of methyl oleate with only a slight loss of activity for at least 10 h; cross-metathesis of Dimethyl Maleate with methyl oleate ceases after 3 h, but the catalyst remains active for methyl oleate metathesis. The reasons for this unusual behaviour are explored and a practical system for the cross-metathesis of methyl oleate with Dimethyl Maleate, under batch conditions, is described.

  • photoinitiator free uv grafting of styrene a weak donor with various electron poor vinyl monomers to polypropylene film
    Polymer International, 2005
    Co-Authors: Duc N Nguyen, Samuel B Adeloju
    Abstract:

    This study investigated the possibility of using styrene, a weak donor forming donor(D)/acceptor(A) pairs with electron-poor (EP) vinyl monomers, for initiating spontaneous photopolymerization and photografting of the copolymers onto polypropylene. Maleic anhydride (MA), methyl methacrylate (MMA), methyl acrylate (MAC), Dimethyl Maleate (DMMA), acrylonitrile (AN) and acrylic acid (AA) were the EP monomers used. Grafting yields together with FTIR analyses were used to confirm the presence of grafting. Styrene/MMA and styrene/AN systems achieved significant grafting, but such levels of grafting were not observed in the styrene/MAC and styrene/DMMA systems. No grafting was observed for styrene/AA or styrene/MA systems, but the latter system underwent photopolymerization. The effect of solvents on grafting was evaluated on styrene/MMA and styrene/AN systems and Dimethylformamide (DMF) was found to retard grafting of both D/A systems. In contrast, chloroform and methanol enhanced grafting of the styrene/AN system although these two solvents had no significant effect on the grafting of the styrene/MMA system.
