    In this thesis, the possibility of grafting poly N-Vinylimidazole (PNVI) onto pullulan was investigated under homogenous and heterogenous conditions using potassium persulphate (KPS) and cerium(IV) ammonium nitrate (CAN) ...
  • Graft Copolymerization of Benzyl Methacrylate onto Alginates 
    Shakir, Ameer Piro (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2013-07)
    Homopolymerization of benzyl methacrylate has been studied by UV initiation using 25 mg DMPA with 2.5 ml BzMA and 0.5, 2.5 mL hexane for different time intervals. The maximum conversion value 99% has been obtained. ...
  • Grafting of Poly [(2-Diethylamino)Ethyl Methacrylate] onto Chitosan 
    Yahya, Kovan Ibrahim Ali (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2014-01)
    In this study, chitosan was grafted with poly[(2-diethyl amino)ethyl methacrylate] in homogeneous and heterogeneous systems by using potassium persulphate as the initiator. The effect of temperature, time, (2-diethyl ...
  • Grafting of poly (2-Hydroxyethyl Methacrylate) onto chitin beads 
    Mohammed, Dana Ali Kader (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2014-07)
    Chitin was grafted with poly(2-hydroxyrthyl methacrylate) poly(HEMA) by using ceric ammonium nitrate (CAN) as the initiator. The effect of temperature, time, concentration of the monomer (HEMA), the amount of chitin beads ...
  • Grafting of Poly (4-Vinyl Pyridine) onto Chitin under Heterogeneous Conditions 
    Hadi, Jihad Mohammed (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2014-08)
    Chitin gel beads were prepared, crushed into powder and grafted with poly(4- vinylpyridine) (P4VP) under nitrogen gas by using cerium ammonium nitrate(CAN) as a redox initiator under heterogeneous conditions in toluene. ...
  • A Miscibility study on pullulan/poly (Ethylene Glycol) blends 
    Birjandi, Elahe Malaki (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2013-07)
    Miscibility of pullulan and poly(ethylene glycol) in aqueous solution has been determined by dilute solution viscometry. Blends of different compositions (100/0, 80/20, 50/50, 20/80, 0/100) with respect to pullulan/poly(ethylene ...
  • Poly(N-hydroxyethyl acrylamide) / Chitosan Based Hydrogels 
    Bahramzadeh, Ehsan (Eastern Mediterranean University - Doğu Akdeniz Üniversitesi, 2019-01)
    Poly(N-hydroxyethyl acrylamide) (polyHEAA) was grafted onto chitosan in aqueous acidic medium using potassium per sulphate initiator to obtain polymer surfaces with blood compatibility for potential biomedical applications ...
  • Preparation and characterization of phosphorylated chitosan films via graft copolymerization 
    Mizwari, Zirar Mohammed Taher (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2013-07)
    Graft copolymerization of bis (2-methacryloyl oxy ethyl) acid phosphate (BAP) on to chitosan initiated by potassium per sulphate (KPS) under N2 atmosphere has been studied. The effect of polymer concentration, monomer ...
  • Preparation and characterization of porous chitosan tripolyphosphate gel bead
