The synthesis of ion-exchange resin which can be used in various separation and chemical purposes, such as diffusion dialysis, electro dialysis, electrolysis and fuel cells has of considerable interest. For all these applications, the interactions of the ionic groups and the resulted morphologies are critical for establishing the unique properties. Considerable researches have been continued to understand the microstructure of these materials. The aim of this study is to synthesize polypropylene (PP) based ion exchange resins and to investigate their ion-exchange properties. In the first part of this study polypropylene was functionalized by grafting maleic anhydride onto the polypropylene and the product was characterized by ATR. The effect of maleic anhydride introduced to the grafting medium and the effect of the radical initiator on the maleic anhydride content of the MA-g-PP samples were investigated. In the second part, neutralization of the MA-g-PP samples with Na+, K+, Mg2+ and Ca2+ ions and peroxide cross-linking of neutralized MA-g-PP samples were performed. Characterization of the neutralized MA-g-PP samples were performed by ATR and SEM-EDX. In the last part of the study, ion exchange properties of MA-g-PP resins towards Cu2+, Co2+, Cd2+, Pb2+ and Fe3+ ions at different pHs were investigated by batch equilibrium method. Rate of metal uptake, concentration effect on the metal uptake and regeneration of the MA-g-PP samples were also examined.

Syntheses of benzotriazole bearing donor acceptor type random copolymers for full visible light absorption
Öktem, Gözde; Toppare, Levent Kamil; Department of Chemistry (2011)
The synthesis and preliminary optoelectronic properties of a series of donor-acceptor (DA) type polymers differing by the acceptor units in the polymer backbone were investigated. Polymers CoP1, CoP2 and CoP3 were designed to yield alternating DA segments with randomly distributed different acceptor units along polymer backbone. The combination of neutral state red colored and neutral state green colored materials resulted in different neutral state colors with respect to their additional acceptor unit. 5,8...
Synthesis and characterization of waterborne silane coupling agent containing silicone-acrylic resin
Akın, Özlem; Aras, Leyla; Department of Polymer Science and Technology (2004)
In this study, waterborne silicone-acrylic resin was produced by incorporating silane coupling agent onto the acrylic main chain by emulsion polymerization. After applying different emulsion polymerization processes, batch polymerization was selected to obtain the resultant resin. Thus finding the optimum conditions by investigating the parameters of monomer ratios, initiators, concentrations of initiators, temperature and time, the novel resin was synthesized. Water-dispersed silicone-acrylic resin was pro...
Synthesis, characterization and electrical properties of diazophenylene and diazodiphenylene bridged co, ni, cu, ce, and er phthalocyanine polymers
Alkan, Cemil; Alkan, Cemil; Department of Polymer Science and Technology (2004)
In this research, diazophenylene and diazodiphenylene bridged metal-phthalocyanine polymers were produced from diazonium salt of diaminophenylene/bensidin and pre-synthesized tetraamino metal phthalocyanines. Tetraamino metal phthalocyanine complexes of Co, Ni, Cu, Ce, and Er were obtained by reducing tetranitro metal phthalocyanine complexes synthesized from 3-nitrophthalic anhydride, urea, metal salt, and ammonium molybdate catalyst. Complexes and polymers were characterized by Fourier Transform Infrared ...
Synthesis, characterization and electrochromic properties of conducting copolymers of terephthalic acid bis-(thiophen-3-ylmethyl)thioester with thiophene and pyrrole and conducting polymer of 1-(4-fluorophenyl)-2,5-di(thiophen-2-yl)-1h-pyrrole
Türkarslan, Özlem; Toppare, Levent Kamil; Department of Chemistry (2006)
Terephthalic acid bis-(thiophen-3-ylmethyl)thioester (TTMT) was synthesized via the reaction of thiophen-3-ylmethanethiol with terephthaloyl dichloride. Nuclear magnetic resonance (1H-NMR) and Fourier transform infrared (FTIR) spectroscopies were utilized for the characterization of the monomer. This 3-functionalized thiophene monomer was polymerized in the presence of thiophene (Th) and pyrrole (Py) upon constant potential application in acetonitrile/tetrabutylammonium tetrafluoroborate (TBAFB). The result...
Modified acrylic hydrogels as controlled release systems
Pınardağ, Fatma Esra; Hasırcı, Nesrin; Department of Chemistry (2006)
In this study, pH-sensitive poly(acrylamide-co-acrylic acid) hydrogels were synthesized as controlled release systems in the presence of N,N-methylene bisacrylamide as crosslinker and ammonium persulfate as initiator. A set of hydrogels were used in the form they were prepared. One set of hydrogels were prepared as porous networks by incorporating sodium chloride into the reaction medium and then leaching of it after the completion of polymerization reaction. Two sets of hydrogels were modified by argon-pla...
