Abstract ABSTRACT Hatem Mohamed Nagi Hasan: Chemical Modification Of Some atural Textile Fabrics. Typed and bound thesis: 174 pages, 11 tables, 19 figures , 2012 Keywords: Wool fabric, acrylic monomers, redox initiation, sodi urn perborate , N-bromosuccinimide , grafting, characterization, polymer cmena In this thesis , chemical modification of ”orne natural teA’tile fabrics via grafting reactions was achieved. Concerning this, we focused on grafting of wool fabric beca use limited work had delt with this natural substrate. Given below is the conclusion arrived at from these studies :- I. A Novel Method for Grafting of Various Acrylic Monomers onto Wool Fabrics A new method for synthesis of acrylic graft copolymers usi ng an efficient redox system. In this methr . ..ilt t :: reducing agent is wool and the oxidizing agents is N- bromosuccinimide (NBS) as a novel initiator. Methyl methacrylate (MMA) ViaS used in the initial and greatest part of this work. Different factors affecting the efficiency of the wool / NBS redox ’stem and magnitude of the polymer criteria, embracing graft yield, grafting efficiency, homopolymer and total conversion, were eA’tensively tudied. Effect of the nature and concentration of transition metal-ion |
